    Cushion-cut engagement rings are becoming more popular, even challenging the long-time favorite: round diamond engagement rings. Right now, about 8–10% of engagement rings sold are cushion cut, and that number keeps growing each year.

    One big reason is the shape of the diamond itself. A cushion cut diamond looks soft and slightly rounded, almost like a small pillow, which is where the name comes from. Because of this shape, it works well with many different ring styles, metals, and budgets. It rarely looks out of place.

    What is interesting is that in 2026, cushion cut ranks fourth among the most popular diamond shapes. That means it is no longer a rare or unusual choice. Many people are choosing elongated cushion-cut engagement rings today.

    So if you are planning to buy an engagement ring, read this guide. Learn everything about cushion cut rings and decide for yourself, does a cushion cut diamond engagement ring match your preferences, or is a different style a better fit for you? Either way, you will know by the end.

    What is a Cushion Cut Engagement Ring?

    Cushion-cut diamond engagement rings are rings with a cushion-cut diamond at the center. The diamond looks like a pillow, with soft edges and rounded corners, which is exactly where the name comes from.

    The cushion-cut diamond emerged in the 17th century. Back then, electric lighting did not exist, so diamond cutters were researching cuts that sparkled beautifully under candlelight. What they developed were vintage cushion cut diamonds with large, broad facets, designed specifically to catch and reflect the warm, flickering light of a candle.

    It worked. Those vintage cushion-cut engagement rings became the standard for centuries. But as candlelight gave way to electric lighting, cutters noticed a problem. The original large-facet design did not reflect artificial light efficiently. 

    So they went back to work and developed the modern cushion cut diamond. The modern square cushion cut diamond was developed with smaller, more numerous facets, better suited to the lighting conditions we actually live in today. 

    Elongated Cushion vs Square Cushion Engagement Rings

    The modern cushion cut comes with a standard length-to-width ratio of 1:1. It is a clean square shape. So if a ring has a perfectly square cushion diamond in it, it is called a square cushion cut engagement ring. But that ratio is not fixed. Change it, and the ring changes with it. 

    A cushion diamond with a 1.5:1 ratio is no longer square; it is vertically longer, and that is what makes it an elongated cushion cut engagement ring. Elongated cushion-cut engagement rings cover more of the finger area. They create a slimming effect on the hand, and, honestly, they look amazing.

    One thing worth remembering,  these two shapes are not made for everybody. Both can look amazing with the right setting, metal, and design, but to get the most out of either one, the choice has to match the person wearing it.

    People with smaller fingers should lean toward elongated cushion cut engagement rings over square cushion cut engagement rings. The elongated shape gives a more finger-flattering effect; it makes the finger look longer and more slender in a way that a square cushion simply does not. 

    On top of that, elongated cushion cut engagement rings carry a strong vintage character, so if you are a vintage lover, the elongated cushion is practically made for you. At Diagaa, we carry both types. Go to the cushion cut engagement rings collection and see how they actually look in reality.

    Popular Styles of Cushion Cut Engagement Rings

    You can create any engagement ring style you want with a cushion diamond; technological advancements have made sure of that. No design is untouchable. But just like a diamond is forever, some engagement ring styles are forever, too. 

    You can modify them, make them more complex or simpler, but you cannot replace them. These ring styles are the foundation of the jewellery world. They work for any diamond shape, and the cushion cut is no exception. These ring styles fall into two categories: traditional and unique.

    Traditional Cushion Cut Engagement Ring Styles

    • Cushion cut solitaire engagement rings - The simplest of all. No extra elements, no distractions, just the cushion diamond doing its thing. Perfect for minimalists and traditional lovers who want the stone to be the whole story.

    • Cushion halo engagement rings - This style wraps the cushion diamond in a layer of smaller diamonds. From above, the center stone and surrounding diamonds blend and look like one big, brilliant diamond. Full of sparkle and perfect for the fashionista who loves light more than the shape of the stone itself.

    • Vintage cushion cut engagement rings - This is where the cushion cut feels most at home. The cushion cut was born in the candlelit 17th century; milgrain edges, engraved bands, and filigree details are not just decorative here, they are historically accurate.

    Unique Cushion Cut Engagement Ring Styles

    • Old mine cut cushion engagement rings - The original version of this shape. Hand-faceted, slightly irregular, and warmer in character than any modern cushion cut. If vintage is what you want, an old mine cut is the most authentic way to get there.

    • Cushion cut three stone engagement rings - The most romantic style on this list. The symbolism of three stones meets the warmth of a cushion diamond, past, present, and future in one ring. Perfect for romantic couples with a retro taste.

    • Cushion cut hidden halo engagement rings - For buyers who want the size boost of a halo without the ring looking too ornate. The halo sits beneath the center stone, invisible from above but visible from the side. All the benefit, none of the loudness.

    Cushion Cut Engagement Rings by Carat Size

    Whenever it comes to shopping for diamond engagement rings, people always ask, " Which carat should I buy?” But believe us, carat weight is not just about budget. Let's assume you have no budget limit. You could even wear the Kohinoor. But think about how it will actually look on you. 

    Sometimes a 1-carat diamond engagement ring looks better than a 10-carat diamond ring. It is not about what size, it is about which size. So first, learn which carat works for your hand. At Diagaa, we carry cushion-cut engagement rings ranging from 0.5 ct to 4 ct. Let's find out which one has your name on it.

    1 carat cushion cut engagement ring  

    The most popular starting point. It fits beautifully on most finger sizes without overwhelming the hand. If you are unsure where to begin, this is the safest and most balanced choice. 

    • Perfect for - First-time buyers, people with petite or average finger size, and anyone who wants elegance without going overboard.

    1.5 carat cushion cut engagement ring 

    Adds visible presence without crossing into statement territory. A particularly strong choice in an elongated cushion, where the shape spreads the diamond further across the finger than the carat weight alone would suggest. 

    • Perfect for - People with average to medium finger size who want a noticeable upgrade from the standard without a dramatic jump in price.

    2-carat cushion-cut engagement ring 

    This is where the cushion cut's deep facets really come alive. The light behaviour at this size is richer and more complex. It makes an impact without needing any help from the setting. 

    • Perfect for - people who want a ring that gets noticed, confident wearers with medium to larger fingers, and buyers who are willing to invest in the stone itself.

    3-carat cushion-cut engagement ring 

    A bold choice. At this size, the setting matters more; a slim band will look unbalanced. A halo, bezel, or wider shank carries the diamond properly. 

    • Perfect for -  people with longer or wider fingers, buyers who want a genuine statement piece, and those who prefer the ring to do the talking.

    4-carat cushion-cut engagement ring 

    For those who want to make a statement that cannot be missed. At this size, the cushion cut's warmth and depth are at their absolute peak. 

    • Perfect for - larger hands where the diamond has room to sit proportionally, and buyers for whom size and presence are the top priority.

    Cushion Cut Engagement Rings by Metal

    Every engagement ring is made up of a few standard elements: the gemstone, the setting, and the metal. To find the right ring, you need to evaluate all three. But the catch is that you can create dozens of combinations out of them, and what works beautifully with one diamond shape does not always work the same way with another. 

    What goes well with a round diamond will not be as effective with a cushion diamond. This rule affects your metal choice, too. Metal is not just about the overall look of the ring; it also needs to match your lifestyle. Let's find out which metal is the right fit for your cushion-cut engagement ring.

    Platinum cushion cut engagement rings

    Platinum is the brightest and most durable metal available. It does not fade, does not require replating, and its cool white tone creates a sharp contrast against the cushion diamond that makes the stone pop. It is heavier than gold and more expensive, but it is also the most low-maintenance option over a lifetime of wear.

    • For buyers who want the most durable option and do not mind paying a premium for it.

    White gold cushion cut engagement rings 

    White gold looks almost identical to platinum at first glance, but costs noticeably less. The difference is that white gold needs replating every few years to maintain its bright finish. 14k white gold cushion cut engagement rings are the most popular choice in this category, strong enough for daily wear and easier on the budget than platinum. 

    • For buyers who want the platinum look without the platinum price.

    Yellow gold cushion cut engagement rings

    Yellow gold is the most traditional metal choice and the one that suits the cushion cut's vintage character most naturally. A cushion diamond in a yellow gold setting looks warm, rich, and timeless. 14k yellow gold is practical for daily wear, while 18k gold cushion cut engagement rings carry a deeper, richer colour at a slight premium. 

    • For vintage lovers, buyers drawn to a warm and traditional aesthetic, and those who want a ring with a classic feel.

    Rose gold cushion cut engagement rings  

    Rose gold is the most romantic metal on this list. The warm blush tone pairs naturally with the cushion cut's soft edges and deep sparkle. It is one of the most chosen metals for cushion cut rings right now and has been trending consistently into 2026. 

    • For modern buyers who want warmth and romance in the metal itself, and anyone who wants a ring that photographs beautifully.

    Cushion Cut Engagement Rings Diamond Types

    Metal sorted. Now comes the decision that will affect your budget more than anything else: the stone itself. Today, the market has more stone options than ever before. And honestly, they can all look identical to the untrained eye. But looks are not the only difference. 

    The diamond type you choose affects your budget, your values, and how the ring holds up over time. Here is what each option actually means.

    Natural cushion cut diamond engagement rings

    Natural diamonds form deep within the earth over billions of years. Their rarity and natural origin make them the most traditional and valuable choice. They also tend to be the most expensive option, but for many buyers, the geological story behind the stone is part of what gives the ring meaning.

    • For buyers who value rarity, natural origin, and long-term value.

    Lab-grown cushion-cut engagement rings

    Lab-grown diamonds are chemically and visually identical to natural diamonds. The only difference is their origin: they are created in controlled laboratory environments rather than underground. They usually cost 60–80% less than natural diamonds of similar size and quality.

    • For buyers who want the look and durability of a diamond at a more accessible price.

    Moissanite cushion cut engagement rings 

    Moissanite is a separate gemstone known for its strong sparkle and rainbow fire. It reflects more colorful light than diamonds and is considerably more affordable. While it is not a diamond, it remains durable enough for everyday jewellery.

    • For buyers who want maximum sparkle with a lower budget.

    Cubic zirconia cushion cut engagement rings 

    Cubic zirconia is the most budget-friendly option. It resembles a diamond at first glance but is softer and tends to lose its brilliance over time. Because of this, it is often used for temporary or fashion rings rather than lifelong pieces.

    • For buyers looking for a diamond, look at the lowest possible price or for short-term use.

    Champagne cushion cut engagement rings

    Champagne diamonds carry subtle golden or brown tones that feel rich and slightly mysterious. In a cushion cut, these tones become even more noticeable because of the cut’s deeper facets.

    • For buyers who want something distinctive but still elegant, champagne cushion diamonds offer a beautiful alternative to traditional white stones.

    Colored gemstone cushion engagement rings

    Not every cushion-cut engagement ring needs to feature a diamond. Sapphire, morganite, emerald, and even colored moissanite stones can be cut into the same soft pillow shape.

    • These rings often appeal to buyers who want a personal or symbolic gemstone rather than a traditional diamond.

    Note: If you want an affordable colored cushion gemstone ring, then you should check out our colored lab diamond cushion engagement rings.

    Cushion Cut Engagement Rings for the Target Audience

    Different ring styles naturally suit different hands and preferences. A ring that looks perfect on one person may feel overwhelming to someone else. Understand which design works best for you to make the decision much easier.

    Cushion-cut engagement rings for women

    Cushion diamonds have a soft, romantic character that many people associate with classic engagement rings. Their rounded edges make them elegant. Because of this balance, they remain one of the most versatile diamond shapes for women’s engagement rings.

    Petite cushion cut engagement rings

    For smaller hands or slender fingers, a very large diamond or wide band can overwhelm the hand. Petite cushion engagement rings usually feature smaller diamonds, thinner bands, and lighter settings. These proportions keep the ring comfortable while still highlighting the beauty of the diamond.

    FAQs - Cushion Cut Engagement Rings

    What is a cushion cut engagement ring?

    A cushion cut engagement ring features a diamond shaped like a soft square with rounded corners, similar to a small pillow. This shape blends vintage character with modern sparkle, which is why it has remained popular for generations.

    Elongated cushion vs square cushion, which should I choose?

    Square cushion diamonds have equal length and width, giving them a balanced and classic look. Elongated cushion diamonds are slightly longer, which can make the finger appear slimmer and the stone look larger. The right choice usually depends on personal style and hand shape.

    Lab-grown vs natural cushion cut engagement rings, which is better?

    Both options offer excellent beauty and durability. Natural diamonds form inside the earth over millions of years, while lab-grown diamonds are created in controlled laboratories. Lab-grown diamonds are typically more affordable, but still provide the same sparkle and strength.

    Which is the best setting for a cushion cut diamond?

    Solitaire and halo settings are among the most popular choices. A solitaire setting keeps the design simple and highlights the center diamond, while a halo setting surrounds the stone with smaller diamonds to increase sparkle and make the center appear larger.

    Can I customize my cushion-cut engagement ring at Diagaa?

    Yes. Diagaa offers customization options that allow you to choose the diamond type, metal, setting style, and other design details. This makes it possible to create a cushion cut engagement ring that reflects your personal style and story.

    How to Tell If Gold Is Real: 13 Proven Tests Ranked by Accuracy

    by Diagaa Staff on Jun 03 2026
    The fastest way to tell if gold is real is to look for a hallmark stamp. Genuine gold pieces sold in the U.S. are legally required to carry a karat stamp, 10K, 14K, 18K, and so on. If the stamp is there and legible, that's your first signal. But hallmarks can be forged, faded, or outright missing, which is why knowing the full range of at-home and professional tests can save you from costly mistakes. This guide walks you through all 12 methods,  from the ones you can do in 30 seconds with a kitchen magnet to the professional-grade XRF analysis used by refineries and jewelers. By the end, you'll know exactly how reliable each test is, and which combination gives you the most.  Check the Hallmark First: Start Here Before Anything Else The hallmark is the single most important thing to look for when checking if gold is real. It's a tiny stamped number, usually found inside a ring band, near the clasp of a necklace, or on the back of a pendant. Think of it as the metal's ID card. Understanding Karat Stamps: 10K, 14K, 18K, 22K, and 24K Karat tells you how much of the piece is actually gold. Pure gold is 24 karats, meaning all 24 parts are gold. Lower karats mean the gold is mixed with other metals like copper, silver, or zinc,  usually to make it stronger or more affordable. Reading Number Stamps: 417, 585, 750, 916, 999 Jewelry made in Europe or other countries often uses a three-digit number instead of a karat stamp. These numbers show how many parts out of 1,000 are pure gold: 417 = 10K gold 585 = 14K gold 750 = 18K gold 916 = 22K gold 999 = 24K gold So if you buy a ring in Italy and see "750" stamped inside, you're looking at 18-karat gold. Both systems mean the same thing,  just written differently depending on where the piece was made. What If There's No Stamp at All? No hallmark doesn't automatically mean the piece is fake. Very old antique jewelry, made before hallmarking rules existed, may have no stamp. Some handmade pieces are also unstamped. But for any modern piece without a hallmark, treat it as unverified and run more tests before trusting it. The Magnet Test: Quick, Free, and Easy Gold is not magnetic. If you hold a strong magnet, the kind you can buy at any hardware store for a couple of dollars, next to a piece of real gold, nothing will happen. The jewelry won't move, pull, or stick. If the piece is attracted to the magnet or jumps toward it, that's a clear sign the metal contains iron, steel, or nickel, none of which are gold. The piece might still have a thin layer of gold plating on the outside, but the inside is not solid gold. One thing to keep in mind:  Some fake metals are also non-magnetic. Copper, brass, and aluminum won't stick to a magnet either. So passing the magnet test is a good sign, but it doesn't confirm gold on its own. Take this test as your first filter, not your final answer. The Weight Test: Does It Feel Heavy Enough? Real gold is surprisingly heavy. If you pick up a piece of genuine gold jewelry, it should feel noticeably solid and weighty in your hand, heavier than you'd expect for its size.  Gold is nearly twice as heavy as silver by volume and about eight times heavier than aluminum. A fake gold ring made from brass or zinc will feel noticeably lighter. This test works best when you have something to compare it to. For a more precise weight-based test, try the density test next. The Density Test: A Simple Science Experiment at Home The density test is more reliable than simply holding the jewelry and guessing whether it feels heavy. When you place a gold item in water, it pushes some water out of the way. The amount of water it pushes aside tells you how much space the item takes up (its volume). Then you compare: How much the item weighs How much space does it occupy This gives you a number called density. Every metal has its own density. Gold is much denser than metals such as brass, copper, or aluminum. So if the density you calculate is close to gold's density, there's a good chance the item is real gold. If the number is far lower, it may be made from a different metal or only coated with gold. How To Do a Density Test Weigh your jewelry on a kitchen scale and write down the number in grams. Fill a tall glass or measuring cup with enough water to fully cover the piece. Note the water level in milliliters. Tie a thin string to the piece and lower it fully into the water without letting it touch the sides or bottom. Note the new water level. Subtract the original level from this new level. That difference is the volume of your piece in cubic centimeters. Divide the weight by the volume. The result is the density. Density Of Real Gold Types Metal Density  Pure Gold (24K) 19.3 18K Gold ~15.5 14K Gold ~13.1 10K Gold ~11.6 Look for Wear and Color Changes Real gold does not tarnish, rust, or corrode. It stays gold-colored for life, whether it's sitting in a jewelry box or buried in the ground for thousands of years. Fake gold will eventually show its true colors, literally. Check the edges of rings, the back of pendants, and anywhere the piece bends or rubs against skin. These high-wear spots are where gold plating wears off first. If you see silver, copper, or a greenish tint peeking through beneath the gold surface, the base metal underneath is showing. The Ceramic Scratch Test: Simple and Surprisingly Accurate Find an unglazed ceramic tile or plate, the kind with a rough, dull underside, not the shiny glazed surface. Drag the piece of jewelry firmly across it and look at the streak it leaves behind. Real gold leaves a gold-colored streak. Fake gold, fool's gold (iron pyrite), and most base metals leave a black or dark gray streak.  But remember, this test does leave a tiny scratch on the jewelry, so use it on a hidden spot. It's a good mid-tier test, simple, free, and more reliable than a magnet or water test. Just don't use it on pieces with sentimental value unless you're comfortable with a small mark in an unseen area. The Water Test: Drop It In and Watch This test is the simplest of all. Drop the piece into a glass of water and watch what happens. Real gold sinks fast and straight to the bottom. It's dense enough that there's no hesitation. A gold-colored fake piece made from lighter metals may still sink, but more slowly. Hollow pieces or anything made from very light material may float or drift down gradually. Nevertheless, the water test won't tell you everything. But it takes five seconds and costs nothing, which makes it a useful first check when you don't have anything else on hand.  The Vinegar Test: A Kitchen Acid Check White vinegar contains acetic acid, a mild acid that reacts with most common metals. Real gold, however, doesn't react to it at all.  Apply a few drops of plain white vinegar onto the surface of the jewelry, or soak the piece in vinegar for about 15 minutes. Then rinse it off and look closely. If the surface changes color, darkens, or shows any kind of reaction, the metal is not solid gold. Real gold will look the same as it did before. Check for Skin Discoloration Wear the piece for a few hours and then look at the skin underneath it. Real gold, especially high-karat gold, doesn't react with your skin. It won't leave any marks or cause any discoloration. If you notice a greenish tint on your skin, that's copper leaching out of the metal and reacting with the natural acids in your sweat. A black mark usually means the metal is reacting with sulfur in sweat or skincare products. Neither happens with high-purity gold. One thing to note:  Even genuine 10K or 14K gold contains copper and other metals, so it can occasionally cause mild discoloration in people who have naturally acidic skin. This test works best as supporting evidence alongside other tests, not as a standalone verdict. The Sound Test: For Coins and Gold Bars Only This test doesn't apply to jewelry, but it's remarkably useful for gold coins and bullion. When you tap a real gold coin against a hard surface or flick it with your finger, it produces a clear, high-pitched ringing sound that lingers for a moment. Base metal coins make a dull, flat thud; the difference is immediately obvious once you've heard both. Gold's inner structure creates that clear, musical tone. Tungsten, a metal sometimes used to fake gold bars because it has a similar weight, can mimic gold's density but not its sound. Even a trained ear can often pick up the difference. If you're buying gold coins and want to do a quick authenticity check before anything else, this test costs nothing and takes two seconds. The Acid Test: The Most Reliable Home Method The acid test has been used by jewelers and gold traders for centuries; it's even the origin of the phrase "acid test," meaning a definitive check. You can buy an acid test kit from most jewelry supply stores for around $20 to $40. The kit includes a small black testing stone and several vials of nitric acid, each calibrated to a different karat level. Here's how it works: Rub the piece on the testing stone to leave a small streak of metal. Apply a drop of acid to the streak. Watch how the streak reacts. If you get: No reaction - high-purity gold, likely 18K or above Milky or cream-colored reaction - silver present in the metal Green reaction - base metals like copper, brass, or zinc are present No reaction on the stone, but the metal itself changes color - gold-plated piece Full kits come with multiple acids for different karat levels, so you can narrow down the purity fairly precisely. This is the most accurate test you can do at home without professional equipment. Most importantly, always wear gloves and work in a well-ventilated space. Nitric acid is corrosive; it needs to be handled carefully. Professional XRF Testing: The Gold Standard At the very top of the accuracy scale is XRF testing, short for X-ray fluorescence. This is what professional gold dealers, refineries, and serious jewelers use when they need a definitive answer. How XRF Machine Works The XRF machine shoots a beam of X-rays at the metal. Those X-rays cause the atoms in the piece to release their own energy back, and every element releases energy at a slightly different frequency, like a unique fingerprint.  The machine reads those frequencies and tells you exactly what the metal is made of, down to fractions of a percent. A result might look like: "58.3% gold, 21.4% silver, 20.3% copper," which translates to 14-karat gold. The machine leaves no marks, uses no acids, and gives a result in seconds. The machine costs between $15,000 and $40,000, so you won't be buying one, but many jewelry stores, coin shops, and pawn shops offer XRF testing as a paid service, usually between $25 and $75. For any piece worth significant money, this is the test worth paying for. The Specific Gravity Test Specific gravity measures how much heavier a material is compared to the same volume of water. Pure water scores 1.0. Real gold scores between 11.3 and 19.3, depending on its karat,  meaning it's up to 19 times heavier than water. That difference is what makes this test work. You'll need a digital kitchen scale, a glass of water, and a thin string or wire. How to do it: Weigh the piece in the open air. Write this down as the air weight (in grams). Place a glass of water on the scale and press tare to zero it out. Tie a string to the piece and suspend it fully submerged in the water without touching the sides or bottom. A pencil resting across the top of the glass works well as a support. Read the weight on the scale. Write this down as the water weight. Use this formula: Specific Gravity = Air Weight ÷ (Air Weight − Water Weight) What your number means: Metal Specific Gravity Pure Gold (24K) 19.32 22K Gold 17.7–17.8 18K Gold 15.5–15.6 14K Gold 13.0–13.1 10K Gold 11.3–11.6 Announcement:  Every piece of gold jewelry at Diagaa comes with a Hallmark certification, so you never have to wonder. Shop with confidence, because we've already done the checking for you.  Final Verdict No single home test will give you total certainty on its own. The magnet test is quick but limited. The density test takes a few more minutes but gives you real data. The acid test is the closest thing to professional accuracy without paying for professional equipment.  And when the piece matters, when it's an inheritance, a significant purchase, or something you plan to resell, professional XRF testing is the only test that gives you a completely reliable answer. The right approach is layered: start simple, go deeper as needed, and spend the money on professional testing when the stakes are high. Real gold will pass every test. And if it doesn't, you'll be glad you checked.

    750 Stamp on Jewelry: What It Really Means and Why It Matters

    by Diagaa Staff on Jun 03 2026
    What does 750 mean on jewelry? When you pick up a ring, necklace, bracelet, or any other piece of jewelry, you may notice a small three-digit number stamped inside it, such as 750 or 999. Many buyers see these markings but are unsure what they actually mean. A 750 stamp simply means the jewelry is made from 18-karat gold. In other words, it contains 75% pure gold and 25% alloy metals that are added to improve strength, durability, and wear resistance. Because of its balance of purity and durability, 18K gold is one of the most trusted and widely used gold standards in fine jewelry worldwide. But the 750 stamp is more than just a number. It represents a globally recognized gold purity standard backed by centuries of craftsmanship, strict manufacturing standards, and precious metal regulations. In this guide, you'll learn exactly what the 750 hallmark means, how it compares to other gold purity markings, how to verify its authenticity, and whether 750 gold is the right choice for your jewelry purchase. What Is the 750 Gold Hallmark and Where Does the Number Come From? The number 750 is not arbitrary. It comes from the millesimal fineness system, a method used to measure how much pure gold a piece of jewelry contains out of 1,000 parts. For example, if a piece of jewelry carries a 750 stamp, it means that 750 out of every 1,000 parts are pure gold. In percentage terms, that's 75% pure gold. Now, if we convert that purity into the karat system, it becomes 18K gold. Since 24K gold is considered pure gold, 75% of 24 equals 18. That's why a 750 hallmark and 18K gold mean the same thing. Most Americans are more familiar with the karat system, such as 10K, 14K, 18K, and 24K. However, hallmarks like 417, 585, 750, and 999 are simply another way of expressing the same gold purity standards. For example: Hallmark Karat Pure Gold Content Common Use 999 24K 99.9% Bullion, investment bars 750 18K 75.0%, the fine jewelry standard Engagement rings, heirlooms, fine jewelry 585 14K 58.5% Everyday fashion jewelry 417 10K 41.7%, US legal minimum Mass-market jewelry  One more thing worth understanding is that you will rarely find everyday jewelry made from 999 gold. While 24K gold is the purest form of gold available, it is also extremely soft. A 24-karat gold ring can bend, scratch, or deform much more easily during daily wear. That's why jewelers mix other metals such as copper, silver, palladium, or nickel with gold. In a 750 gold piece, the remaining 25% consists of these alloy metals. They give the jewelry the strength to hold gemstones securely, withstand everyday wear, and last for generations without sacrificing the rich appearance that makes gold so desirable. A Simple Way to Remember Gold Hallmarks A quick rule to remember is to move the decimal point one place to the left. 750 = 75.0% pure gold 585 = 58.5% pure gold 417 = 41.7% pure gold This simple trick works for most common gold hallmarks and makes it easy to understand the gold purity of a jewelry piece at a glance. Important Note About 417 Hallmark In the USA, a 417 hallmark means 10K gold, which is the minimum requirement for gold to be classified and sold as gold jewelry. A 417 stamp indicates that the jewelry contains 41.7% pure gold. If the gold content is lower than 10K, the jewelry generally cannot be marketed as solid gold jewelry in the United States. What Does the 750 Stamp Certify? The Hallmarking Process When your jewelry carries a 750 hallmark, it does not just guarantee the purity of the gold; it also suggests that established hallmarking laws and standards have been followed. In the United States, one of the key laws governing precious metal marking is the National Gold and Silver Stamping Act. Under this law, falsely marking jewelry or misrepresenting the purity of a precious metal can lead to legal consequences. Because of these regulations, buyers receive greater protection against fake or misleading gold jewelry. It is also important to understand that a hallmark and a maker's mark are not the same thing. A hallmark indicates the purity of the metal, while a maker's mark identifies the manufacturer, importer, or company responsible for the jewelry piece. Hallmarking is carried out by jewelry manufacturers, independent jewelers, and importers. Many U.S.-based jewelry businesses register their maker's marks as trademarks with the U.S. Patent and Trademark Office (USPTO). Because of this, not every jeweler can legally use another company's maker's mark. The hallmarking process itself involves testing the metal's actual composition, not merely trusting the manufacturer's word. Gold purity may be verified through methods such as X-ray fluorescence (XRF) analysis or acid testing. These testing methods help determine whether the jewelry contains the stated amount of gold and can be useful when verifying authenticity. Although hallmarking systems vary across countries and regions, the purpose remains the same: to verify precious metal purity. In many Asian countries, manufacturers use the AU 750 marking. In some European countries, additional assay office marks are used alongside the purity stamp. Italian jewelry often carries a star mark in addition to the 750 hallmark, which we will discuss in more detail in a later section. No matter where you buy 18K gold jewelry, the 750 stamp should indicate the same thing: 75% pure gold. In simple terms, the 750 hallmark certifies the gold purity of the jewelry and helps establish trust between the maker and the wearer. Let's take a closer look at some of the most common 750 hallmarks. What Does AU 750 Mean?  AU is the chemical symbol for gold, derived from the Latin word aurum. The AU 750 stamp is the same as a standard 750 hallmark. The main difference is the country or region where the jewelry was manufactured. Manufacturers in many Asian countries, including China, South Korea, and Hong Kong, commonly use the AU 750 hallmark on 18-karat gold jewelry. In these markets, placing the metal symbol before the purity number is a standard industry practice. So, AU 750 simply means the jewelry contains 75% pure gold and is equivalent to 18K gold. The purity, quality, and value are the same as any other 750 hallmark. If you have inherited jewelry with this marking or purchased a piece at a U.S. estate sale, you can treat an AU 750 stamp with the same confidence as any other 750 hallmark. What Does Italy 750 Mean on Jewelry? When you see jewelry from a European brand, you will often notice Italy 750 pieces with a small star beside the hallmark. This is because Italy is one of the world's most storied centers of gold craftsmanship, with the Vicenza and Arezzo regions producing an extraordinary volume of gold jewelry that is exported worldwide. The Italian 750 mark does not indicate higher gold purity. The gold is still 18K, or 75% pure gold. What makes Italy 750 jewelry special is Italy's long-standing reputation for craftsmanship, design, and finishing quality rather than a higher gold content. What Does 750 Mean on a Ring - Yellow, White, and Rose Gold? The answer is no. The 750 stamp describes the gold content, not the color. A yellow 750 ring, a white 750 ring, and a rose 750 ring all contain exactly 75% pure gold. What changes between them is the alloy that makes up the remaining 25%.  Now, when we talk about gold colors, there are not just three colors of gold available for jewelry. There are several other attractive gold colors as well. However, yellow gold, white gold, and rose gold are the most widely used because they are easier to produce and have remained popular for generations. No matter what color you choose, all 18K gold jewelry contains the same amount of pure gold and carries the same 750 hallmark. The difference lies only in the metals mixed with the gold to create a specific color and appearance. Want to learn more about the different gold colors available for jewelry? Read our guide: Different Colors of Gold for Jewelry. 750 Gold vs. Other Hallmarks - 18K vs 14K vs 10K Most gold jewelry is made using one of three gold purity standards: 18K, 14K, or 10K gold. As we already know, 18K gold contains 750 parts pure gold out of 1,000. Similarly, 14K gold contains 585 parts pure gold out of 1,000, while 10K gold contains 417 parts pure gold out of 1,000. Although all three are considered real gold jewelry, there are important differences in purity, durability, color, resale value, and price. The comparison below will help you understand which gold purity level is best suited for your needs. Attribute 750 Gold (18K) 585 Gold (14K) 417 Gold (10K) Pure gold content 75% 58.5% 41.7% Color depth Deeper yellow Slightly lighter Noticeably paler Durability Very durable for daily wear Marginally harder and more scratch-resistant Hardest of the three Tarnish resistance Does not tarnish Does not tarnish Can tarnish at alloy sites Hypoallergenic rating Higher  Moderate Lower  Rhodium requirement (white gold) Yes, every 1–3 years Yes, every 1–3 years Rarely used in white gold Price point Higher (more pure gold) More affordable Most affordable Resale liquidity Strongest, highest gold content Moderate Lowest resale value Best for Engagement rings, heirlooms, investment jewelry Everyday fashion ring Mass-market, budget builds How Much Is 750 Gold Worth? USD Value of 18K Gold Jewelry The value of 750 gold depends mainly on the current market price of gold. Since 750 gold contains 75% pure gold, its basic value is calculated using 75% of the current gold price. For example, if pure gold is selling for $100 per gram, one gram of 750 gold would contain about $75 worth of pure gold. Similarly, a 5-gram piece of 750 gold would contain approximately $375 worth of gold. However, jewelry is usually worth more than its gold content alone. When you buy a ring, necklace, or bracelet, you are also paying for craftsmanship, design, manufacturing, branding, and any gemstones used in the piece. That's why a 750 gold ring may sell for much more than its gold value. The gold content provides a baseline value, while the final price reflects everything that went into creating the jewelry. What Happens If You Sell 750 Gold Jewelry? If you decide to sell your 750 gold jewelry in the future, the amount you receive will depend on where you sell it. Pawn shops typically pay less because they need to make a profit when they resell the piece. In many cases, you may receive around 50% to 70% of the gold's actual value. Private gold buyers, estate jewelry dealers, or specialized gold purchasing companies often pay more, sometimes around 70% to 80% of the gold value. This difference can be significant.  For example, on a 10-gram gold piece, choosing the right buyer could mean receiving hundreds of dollars more for the same jewelry. That's why it is always worth comparing multiple offers before selling your gold jewelry.

It explains the key factors to consider and helps you set a budget that fits your needs and priorities. How to Verify a 750 Gold Hallmark If you're buying jewelry from an unknown seller, inheriting a piece, or shopping at an estate sale, it's a good idea to verify that the 750 hallmark is genuine. Here are four common ways to check: 1. Check the Hallmark Look inside a ring band, on a necklace clasp, or near a pendant's jump ring. A genuine hallmark should be clear, evenly stamped, and easy to read. If the stamp looks poorly made, blurry, or appears to sit on the surface rather than being stamped into the metal, it may require further inspection. 2. Use a Magnet Gold is not magnetic. Hold a strong magnet close to the jewelry. If the piece is strongly attracted to the magnet, it may contain steel or other non-gold metals. Keep in mind that this test can only identify obvious fakes. It cannot confirm the exact gold purity because many metals used in gold alloys are also non-magnetic. 3. Get an Acid Test A jeweler can perform a simple acid test to check the gold purity. During the test, a small amount of nitric acid is applied to the metal. Genuine 18K gold reacts differently from lower-karat gold or base metals, allowing the jeweler to estimate its purity. This is one of the most common and affordable testing methods available. 4. Request an XRF Test X-ray fluorescence (XRF) testing is one of the most accurate ways to verify gold purity without damaging the jewelry. The machine analyzes the metal and provides a detailed breakdown of the elements present in the alloy. Who Should Buy 750 Gold Jewelry and What Is It Best For? Every gold purity level has its place, but 750 gold is often the preferred choice for buyers looking for a balance of beauty, durability, and long-term value. If you're buying natural diamond engagement rings, especially one set with diamonds, 18K gold is a popular choice for a reason.  For people with sensitive skin, 18K gold may also be a better option than 14K or 10K gold because it contains fewer alloy metals, which can reduce the risk of skin irritation. For those who want a necklace or bracelet that can be worn daily while reta, 18K gold is the most balanced choice available. How to Care for 750 Gold Jewelry 750 gold jewelry is strong enough to withstand the stresses of daily wear. However, if you do not take proper care of it, it can gradually accumulate dirt, oil, and everyday residue, causing it to lose some of its shine over time. Proper care is essential to preserve the beauty, brilliance, and appearance of your 750 gold jewelry for years to come. Remove jewelry before swimming, cleaning, or using harsh chemicals. Store pieces separately in a soft pouch or jewelry box to prevent scratches. Clean regularly with warm water, mild soap, and a soft cloth. Avoid exposing jewelry to perfumes, lotions, and hairsprays whenever possible. Have gemstone settings inspected by a jeweler once a year. For white gold jewelry, consider rhodium replating every few years to maintain its bright white appearance. Final Thoughts A 750 stamp on jewelry means the piece contains 75% pure gold. The remaining 25% consists of alloy metals that are added to improve durability, strength, and everyday wear resistance. Different countries may use different hallmarking systems and additional markings, but the 750 number always represents the same gold purity standard: 18K gold. In the United States, hallmarking and precious metal marking are regulated to help protect buyers from fraud and misrepresentation. Gold jewelry can carry different hallmark numbers depending on its purity. For example, 18K gold is marked 750, 14K gold is marked 585, and 10K gold is marked 417. So, whenever you buy gold jewelry, make sure to check the hallmark first. It is one of the easiest ways to understand the gold purity of a piece. For added confidence, you can also use the verification methods discussed above to confirm its authenticity. Frequently Asked Questions What is the difference between 750 and 925? A 750 hallmark means the jewelry is made from 18K gold containing 75% pure gold. A 925 hallmark means the piece is sterling silver containing 92.5% pure silver. They represent different metals, not different grades of gold. How much is a 750 gold necklace worth today? The value of a 750 gold necklace depends on its weight, the current gold price, and any craftsmanship or gemstones it contains. Since 750 gold is 75% pure gold, its value rises and falls with the gold market. Why does my gold necklace say 750? A 750 stamp means your necklace is made from 18K gold. The hallmark indicates that the piece contains 75% pure gold and 25% alloy metals added to improve durability, strength, and everyday wear resistance. Is 750 a good quality for jewelry? Yes, 750 gold is considered a premium jewelry standard. It offers an excellent balance of purity and durability, making it a popular choice for engagement rings, wedding bands, and other fine jewelry pieces. How much do pawn shops pay for 18K gold? Pawn shops typically pay less than the actual gold value because they need room for profit when reselling. In many cases, offers range from 50% to 70% of the gold's estimated value, depending on market conditions and the buyer.

    Portuguese Cut Diamond: Meaning, History, Cost & Engagement Rings

    by Diagaa Staff on Jun 02 2026
    You are definitely familiar with diamond cuts like round, oval, and pear, each with 57-58 facets. Maybe you have even worn an engagement ring with one of them. The whole world is very fond of them; they are the visible gems of the diamond world. But what if I told you that you could have that same round diamond, or an oval or a pear, with 161 or more facets? Not 58. One hundred and sixty-one. Can you imagine how different that sparkle would be? This guide is all about that diamond with 161 or more facets. That is called a Portuguese cut diamond. I will tell you so many interesting things about this hidden gem of the diamond world, one that very few people know about.  That is the Portuguese cut diamond. By the end of this guide, you will know everything you need to decide whether a Portuguese cut diamond belongs on your finger. What is a Portuguese Cut Diamond? Before we go further, one thing is important to understand. When you hear oval cut or pear cut, you picture a shape. The Portuguese cut is not a shape; it is a faceting style. It describes a more complex way of cutting a diamond. So you can have the Portuguese faceting style on any diamond whose core shape is rounded, like round, oval, pear, or even an antique-inspired shape. What Makes Portuguese Cut Diamonds Different Diamond is all about light play. In 1919, a young mathematician named Marcel Tolkowsky applied every rule of mathematics and every law of physics to answer one question: what arrangement of facets gives a round diamond the highest possible sparkle?  His answer was 58 facets, with 33 on the crown and 25 on the pavilion, every angle calculated to return the maximum light to your eye. That became the round brilliant cut, and the whole world has loved it ever since. The Portuguese faceting style takes it even further. With 161 or more facets, light inside the diamond does not bounce off a handful of broad surfaces and come back as one wide flash. It travels through many smaller surfaces and returns as dozens of smaller, layered bursts.  As a result, when you move your hand, a Portuguese-cut diamond often produces more small flashes of light, or scintillation, than a traditional round brilliant of similar size. But how did we get from 58 facets to 161? What happened in between, and how did it even become possible to almost triple the facets on a diamond? Let's look into the history to understand that. History of Portuguese Cut Diamonds Well, the story began in the early 18th century, when large diamond deposits were found in the region of Minas Gerais in Brazil, which was a Portuguese colony at the time. Before this happened, India was the primary source of diamonds. This discovery enabled Europe to have a steady supply of diamonds for the first time in history. Huge amounts of rough diamonds started flowing into Lisbon, and Portugal became a vital center of the diamond trade. And naturally, if you have an abundance of resources, you begin to experiment with new ideas. Over time, cutters working with the influx of Brazilian diamonds began experimenting with more complex faceting styles to develop diamonds with more sparkle and beauty. At the time, there were no electric lights, no jewelry-store spotlights, and no camera flashes. Royal palaces, grand halls, and wealthy homes were illuminated by candles, oil lamps, and fireplaces. The light was soft, warm, and often quite dim. Because of this, diamonds had to work harder to reflect light and catch people's attention. So cutters started adding more and more facets to diamonds. This eventually became known as the Portuguese cut. The exact origin of the cut is still debated. Historians cannot point to a single inventor or a specific moment when it first appeared. What we do know is that the style became strongly associated with Portugal, which is why it eventually became known as the Portuguese cut. There is one more important thing to know. There is also a famous stone called the Portuguese Diamond. This diamond is a historic 127-carat gemstone, so don't confuse the Portuguese cut with the Portuguese Diamond. They are completely different things. Now you might be thinking, if Portuguese-cut diamonds were around before the modern round brilliant cut, then why did the industry move in a different direction? Well, that is largely related to finding the right balance between sparkle and practicality. Creating more than 160 facets requires significantly more time, skill, and precision than cutting a standard brilliant diamond. The deeper design can also result in more weight being concentrated below the stone, making it less efficient from a manufacturing perspective. For large-scale commercial production, it simply wasn't the practical choice. Then, in 1919, Marcel Tolkowsky developed the proportions that helped define the modern round brilliant cut. It offered excellent sparkle while also being easier and more practical to produce consistently. That is why we see fewer Portuguese-cut diamonds nowadays. They are not completely gone, but they are rare. Okay, so the history is clear. That brings us to the next question: how is a Portuguese-cut diamond actually created? How a Portuguese-Cut Diamond Is Made  To understand how a Portuguese cut diamond is created, you first need to understand how a diamond is structured. Every diamond has three main parts. The table is the flat facet on the very top,  the surface you look through when you look at a diamond face-on.  The girdle is the thin edge that runs around the middle of the stone, connecting the top and bottom halves.  The pavilion is the entire lower half of the diamond,  the cone-shaped section that sits below the girdle and comes to a point at the bottom. In a traditional round brilliant diamond, the top half,  called the crown, has 33 facets in total. One of those is the table itself. The remaining 32 are arranged across a single main row on the sides of the crown. The pavilion carries 25 facets, arranged across 2 rows. In a Portuguese cut diamond, the structure is significantly more complex. The crown carries approximately 81 facets, one table facet at the top, and the remaining 80 spread across three rows on the sides of the crown.  The pavilion carries approximately 80 facets, arranged across five rows rather than two. And critically, all of these facets are much smaller than those on a round brilliant. More rows, more surfaces, smaller individual facets, that is what creates the layered, kaleidoscopic light effect that makes this cut so distinctive. Creating those small facets requires a level of craftsmanship that very few cutters in the world possess. A round brilliant can be cut by a skilled operator in a matter of hours. A Portuguese cut, done properly, takes many times longer.  Each of the 161 or more facets requires individual placement and individual polishing. And because the pavilion is deeper than a standard cut, the stone also sits lower in its setting,  meaning the cutter has to constantly weigh the trade-off between adding depth for light performance and preserving enough carat weight to make the stone commercially viable. Round Brilliant Diamond vs. Portuguese-Cut Diamond  Feature Round Brilliant Diamond Portuguese Cut Diamond Table 1 facet 1 facet Crown Facets 32 facets across 1 row 80 facets across 3 rows Crown Total 33 facets 81 facets Pavilion Rows 2 rows 5 rows Pavilion Facets 25 facets 80 facets Total Facets 57–58 161+ Facet Size Larger, fewer surfaces Smaller, many more surfaces Cutting Time Hours Many times longer Skill Required Skilled operator Master lapidary The Portuguese cut is not a diamond shape at all;  it's a faceting style. But it is certainly one of the most unusual diamond cuts you can find today. Now, this guide is focused entirely on Portuguese-cut diamonds. But when choosing the perfect diamond for an engagement ring, it is important to consider all the options that might catch your eye. So before we answer whether a Portuguese-cut diamond is right for your engagement ring, let's see how it compares with some other popular diamond styles, including the Heart Shape, Elongated Cut, and Old European Cut. Portuguese Cut vs Rose Cut Feature Portuguese Cut Rose Cut Facets 161+ facets Usually 3–24 facets Sparkle Intense, highly scintillating Soft and subtle Bottom Structure Deep pavilion Flat bottom Appearance Bright and lively Delicate and antique Popularity Today Rare Niche vintage choice Best For Maximum sparkle Antique charm Portuguese Cut vs Old European Cut Feature Portuguese Cut Old European Cut Facets 161+ facets 57–58 facets Sparkle Style Many small flashes Larger, broader flashes Origin Associated with 18th-century Portugal Late Victorian and Edwardian era Appearance Complex and modern-looking Warm vintage character Availability Very rare More commonly found in antique jewelry Best For Unique light performance Historic appeal Portuguese Cut vs Elongated Cuts Feature Portuguese Cut Elongated Cuts (Oval, Pear, Marquise) Type Faceting style Diamond shapes Main Appeal Extraordinary sparkle Elegant elongated shape Facets 161+ facets Usually 57–58 facets Finger Coverage Depends on shape Appears larger on the finger Availability Rare Widely available Best For Buyers seeking uniqueness Buyers seeking a flattering silhouette Now that we've seen how Portuguese-cut diamonds compare to other popular diamond styles, let's look at some of the practical considerations that matter when you're actually buying one.  How Much Does a Portuguese-Cut Diamond Cost? The cost of a Portuguese-cut diamond is not a simple question to answer. Yes, they are rare and very hard to make. However, their price does not depend solely on their rarity and craftsmanship. But their price does not depend solely on their rarity and craftsmanship. Most Portuguese-cut diamonds are cut by specialist lapidaries, which means their pricing can vary significantly from one stone to another. Still, the final price depends heavily on the same factors that determine the value of any diamond: the 4Cs (carat, cut, color, and clarity), as well as whether the diamond is natural or lab-grown. Here, the biggest challenge is often not the price but the availability. Because Portuguese-cut diamonds are so uncommon, finding one can be far more difficult than finding a comparable round, oval, or cushion diamond. So my final verdict is simple: if you want to know the exact price of a Portuguese-cut diamond, your best option is to contact a reputable jeweler or reliable diamond dealer and ask for pricing on specific stones. Can Portuguese Cut Diamonds Be Made In a Lab Yes, Portuguese-cut diamonds can be lab-grown. In fact, Many of the Portuguese-cut diamonds marketed today appear to be lab-grown, and there is a practical reason behind that. Since this type of diamond is already expensive to produce, jewelers often use lab-grown diamonds to keep prices more affordable.  After all, lab-grown diamonds cost less than natural diamonds while offering the same sparkle and visual appearance. Additionally, specialty cuts like the Portuguese cut demand more from the rough diamond. Cutters need a larger and cleaner section of rough material, along with significantly more cutting work, to create all those extra facets. As a result, relatively few natural diamonds are cut in the Portuguese style. This means that even if you find a natural Portuguese-cut diamond, your options in terms of carat weight, clarity, color, and shape may be quite limited. Naturally, lab-grown diamonds become an attractive option for both manufacturers and buyers. Manufacturers can produce them in greater quantities, while buyers get access to larger stones, more shapes, and a wider range of clarity grades without stretching their budget. Best Settings for a Portuguese-Cut Diamond  So far, we've covered almost everything there is to know about Portuguese-cut diamonds, their history, how they are made, how much they cost, and even whether a lab-grown version makes sense. That brings us one step closer to answering the big question: Is a Portuguese-cut diamond the right choice for your engagement ring? But before we get there, there is one important detail worth discussing. No matter how beautiful a diamond is, it still needs the right setting to show off its sparkle and keep it secure. After all, the setting is what holds the diamond in place and plays a big role in the overall look of the ring. The good news is that Portuguese-cut diamonds work well with most popular ring settings. However, solitaire and halo settings do a better job of showcasing the cut's unique sparkle and beauty than others.  Is a Portuguese-Cut Diamond Right for Your Engagement Ring? After everything we've discussed, you might be wondering whether a Portuguese-cut diamond is actually the right choice for an engagement ring. The answer is simple: it depends on what you're looking for. If you want a traditional diamond that everyone else chooses, is available easily, and want a less expensive engagement ring, then a round brilliant, oval, or cushion cut will probably make more sense.  But if you want something different, something that makes people stop and ask, "What cut is that?", but if you want something rare, unusual, and capable of producing a sparkle pattern most people have never seen before, then a Portuguese cut diamond ring is definitely worth considering.  Also Read About Elongated Cushion Cut Engagement Ring Oblong Diamond Engagement Ring Oval Cut Engagement Ring Frequently Asked Questions Does a Portuguese-cut diamond look bigger? Not necessarily. Portuguese-cut diamonds typically have a deeper pavilion to accommodate their many facets. Because more of the diamond's weight is concentrated below the surface, they may actually face up slightly smaller than some other cuts of the same carat weight. Is a Portuguese-cut diamond more expensive? It can be. Portuguese-cut diamonds require significantly more cutting and polishing work than standard brilliant cuts. However, the final price still depends on factors such as carat weight, color, clarity, certification, and whether the diamond is natural or lab-grown. Why is it called a Portuguese-cut diamond? The exact origin of the cut is debated, but it became strongly associated with Portugal during the 18th century when Brazilian diamonds were flowing into the country. Over time, the faceting style became known as the Portuguese cut because of that connection. How do you determine the quality of a Portuguese-cut diamond? Just like any other diamond, quality is largely determined by the 4Cs: carat, cut, color, and clarity. For Portuguese-cut diamonds, you should also pay close attention to facet symmetry, polish quality, and how evenly the stone reflects light.
