Halloween-Proof Your Jewelry: What to Wear (and Skip) at Parties

Halloween party jewelry should be something you don't have to worry about. You shouldn't feel bad if it gets lost, broken, or stolen. Halloween parties are full of fun, dancing, jumping, and excitement, so losing a piece of jewelry is always possible. That's why we recommend wearing affordable jewelry, like imitation pieces made with diamond simulants and plated metals. Do not wear your most expensive pieces and leave them at home. Need ideas? Check out our Halloween Jewelry Ideas guide for 30 fun pieces to wear to a Halloween party. Want to wear fine jewelry instead, like the pieces you wear to your everyday parties? Don't worry! We'll help you find the perfect piece. Costume Jewelry Is the Smarter Choice If you want jewelry that won't ruin your party mood if it gets lost or damaged, costume jewelry is a good choice. It's usually affordable, so you won't feel as bad if it gets scratched, dirty, or lost. However, some costume jewelry can cause skin irritation because of the metals used to make it. When buying jewelry, check that it's made from skin-friendly materials. Choosing nickel-free pieces can help reduce the risk of irritation. What a Halloween Party Does to Jewelry That an Ordinary Party Doesn’t At a dinner party, you dress up and enjoy the evening. But at a Halloween party, you become someone else. You might dress as a vampire, Wolverine, a ghost, or another character. With all the dancing, jumping, and moving around, your jewelry needs to keep up with your costume without getting caught or pulled. That’s why we ask three simple questions before choosing jewelry for Halloween: Could I live with losing or damaging it? Will it stay on? Will it survive the night? Keeping these three questions in mind, here are our recommendations for jewelry to wear to a Halloween party. What to Wear: Halloween Party Jewelry That Holds Up Earrings: Studs with secure backs or small styles that fit close to your ears. Rings: Plain bands or bezel-set rings, where a metal rim holds the stone in place instead of raised prongs. Necklaces: Short, sturdy chains and pendants that sit close to your collarbone. Bracelets: Snug bracelets with secure clasps. A diamond tennis bracelet is a good example of a piece that gets a “wear, but check it” recommendation. Its row of stones sits flat against your wrist, making it a practical choice for a crowded party. However, its flexible links can catch on lace or loose clothing. If it has a safety latch, make sure to fasten it. These tips cover the type of jewelry to choose, but the style depends on your costume, makeup, and party theme. Black-stone jewelry is a popular choice for Halloween. It adds a dark, spooky touch without needing pumpkin-shaped designs or other Halloween-themed pieces. Consider black stones such as onyx or black tourmaline set in white metal. Sterling silver is also an option for a night when you want to keep your jewelry choice simple and affordable. Halloween Party Jewelry by Type of Party Type of party Good bets Leave at home House party with friends Secure studs, a sturdy chain, a snug bracelet Heirlooms, long dangling earrings, loosely set stones Crowded bar or club One small piece you could replace, or costume jewelry Valuable pieces and anything that could be pulled off in a crush Office party, no costume Fine pieces with a quiet nod to the season, such as black or colored diamond studs Very little: this is the lowest-risk setting for fine jewelry Family event or trick-or-treating Simple studs or a plain chain Bracelets, dangling earrings and long necklaces that costumes or small hands can snag Full costume event One real anchor, such as secure studs, with costume jewelry doing the loud work Anything that sits under a wig, a glove or a sleeve Before You Leave: A Five-Step Jewelry Check for Halloween Check your jewelry. Gently tug each piece and check the clasps, stone settings, and earring backs. If anything feels loose, take it to a jeweler before wearing it. Secure your earrings. Some earring backs can come loose easily. Ask your jeweler for backs that hold your earrings more firmly. Put jewelry on last. Apply makeup, hairspray, and perfume before putting on your jewelry. This helps protect delicate pieces and keeps products away from the stones and metal. Take photos of your jewelry. Keep clear photos of the pieces you wear. Also, check your insurance policy to see what it covers if something gets lost or damaged. Choose a safe place for your jewelry. If you need to take something off, put it in a zipped pocket or a small pouch. Avoid leaving it on bathroom counters, in coat piles, or loose in your bag. One Rule to Remember at Any Halloween Party Wear jewelry you can afford to replace, and leave your most valuable pieces at home. Choose jewelry that stays in place, can handle a little wear, and goes well with your costume. And remember to put your jewelry on last. Halloween jewelry should be fun, not something you worry about all night. Secure diamond studs, a snug tennis bracelet, a black diamond pendant, or a custom piece can all be great choices if they fit your outfit and stay secure.

A two-finger ring might look uncomfortable or hard to wear. It’s easy to think it’s just a runway trend that looks good in photos but doesn’t work in real life. But two-finger rings are becoming popular. Fashion brands are making rings that cover two, three, or even four fingers.  Big gold styles have been popular in hip-hop fashion for years, and simple versions can cost as little as $20. So, can you actually wear one? Yes! It mostly depends on how well the ring fits and which two fingers you wear it on. What Is a Two-Finger Ring? 5 Types You Should Know A two-finger ring is one piece of jewelry that sits across two fingers instead of just one. It can have two connected bands, an open design, or one large piece that covers both fingers. It’s also called a double-finger ring. If it covers three or four fingers, it’s usually called a multi-finger ring. You might also hear the term “Between the Finger,” which Van Cleef & Arpels trademarked in 1974, according to The Jewellery Editor. Although these rings may look similar, they come in different designs. Here are five common types: Type How it looks What to know 1. Connected double band Two rings joined together Both fingers move together, so the fit matters. 2. Open shank A ring with an open design that stretches across two fingers Check that it feels comfortable when you bend your fingers. 3. Double shank, shared top Two bands connected to one decorative top Works well for large, bold designs. 4. Long oval or plate One long piece of jewelry covering two, three, or four fingers Makes a statement but may be harder to wear comfortably. 5. Two separate rings Two rings worn next to each other to look like one Each ring fits its own finger and can be worn separately. Not every ring that covers more than one finger is a true two-finger ring. Some styles simply use two separate rings to create the same look. Why the Two-Finger Ring Trend Emerged Again In September 2026, SCMP reported recent launches from Cartier to Hermès that stretch a ring across two, three and even four fingers, and listed Rick Owens and Jean Paul Gaultier among the houses turning the idea into a statement of scale and attitude.  Hermès isn't new to it. SCMP notes the house has made double-finger rings for more than 20 years under Pierre Hardy, its fine jewellery creative director. The designers it quotes explain the appeal in two ways. Milka Karaagacli of Kismet by Milka says a double-finger ring changes how a hand looks, making it feel stronger and more defined.  So is it just a fad? The easy answer is that jewelry trends come and go. But this one keeps coming back. Jewelry writer Katerina Perez flagged two-finger rings as a trend in 2014. In 2020, The Jewellery Editor argued that multi-finger rings were "here to stay."  And here they are again in 2026. That doesn't prove this wave will last, and nobody can say how long it will. It does suggest the idea has more going for it than a one-season gimmick. From Ancient Rings to Street Gold: A Short History SCMP notes that multi-finger rings were worn in ancient Egypt, where they marked power and protection, and in Hellenistic Greece and Rome, where they signified status.  A ring that spans fingers has been a way of saying "this person matters" for a very long time. Museums collect them, too: The Metropolitan Museum of Art holds a gold double-finger ring by the New York jeweler Marcus & Co. The romantic chapter came later. The Jewelry Editor traces today's big, hand-spanning rings back to the toi et moi rings of the late seventeenth century, which set two stones side by side, one for you and one for me. It recounts Napoléon's 1796 proposal to Joséphine de Beauharnais with a sapphire-and-diamond toi et moi ring. Then the jewelers took over. Van Cleef & Arpels made high-jewelry versions in the early 1970s, with butterflies and flowers set with Mystery Set rubies, and trademarked its Between the Finger name in 1974. And then the street picked it up. SCMP says the double-finger ring resurfaced in hip-hop and punk subcultures in the late twentieth century. Those are the roots of the chunky gold pieces you'll meet in the styles below. What a Two-Finger Ring Means Today The ring finger has long been linked to love and marriage. Two-finger rings, however, don't have any strict rules about what they mean. In the past, rings could represent power, protection, or status. Today, most people wear them simply because they like the style. Two-Finger Ring Styles: Find the One That Looks Like You Lane The look Typical materials Worth knowing Fine and high jewelry Diamond- or gemstone-led, often sculptural. One fine jeweler's version mixes heart, round, and emerald-shaped diamonds in 14K gold Gold, diamonds, gemstones Often made to order Gold classics Chunky rectangles, script lettering, names, religious scenes 10K and 14K gold See the next section Minimal and everyday Slim double bars, clean geometric lines, often adjustable Sterling silver, plated metals The easiest way in. Check whether the finish is plated. Sculptural and artisan One-of-a-kind pieces that read as small sculptures Silver, copper or brass with wood, shell, antler or fossil Natural materials make each piece different Chain-linked and hand jewelry Rings joined by chains, up to the hath phool, a finger ring connected to a bracelet Varies Gold Two-Finger Rings and Hip-Hop Heritage Gold two-finger rings have their own history, especially in old-school hip-hop fashion. They have a bold, chunky look that makes them stand out.  Nugget rings are the chunky rectangular shape you'll see in listings.  Script rings spell out a word like "KING" or "BOSS," or a name.  ID and name rings put a personal identifier front and center.  Last Supper rings carry that religious scene. A diamond-cut finish adds sparkle by faceting the metal's surface. How to Wear a Two-Finger Ring You can wear a two-finger ring on any two fingers next to each other, such as your pinky and ring finger, ring and middle finger, or middle and index finger. Each combination feels a little different, so choose the finger pair that feels most comfortable and looks best on your hand.  Pair Where it sits Worth weighing Pinky + ring Along the outer edge of the hand Often the least intrusive for everyday gripping, but worth testing. It uses the ring finger, so think about a wedding band too. Ring + middle The center of the hand Baunat's suggestion, on the non-dominant hand. Katerina Perez also recommended middle and ring fingers, because the connection between the rings can get in the way of finger use. Middle + index The front of the hand, the most visible spot Leaves the ring finger free for a wedding band. But you use these fingers constantly for pointing and pinching, so test comfort before committing. Note: For the finger names and what wearing a ring on each one traditionally signals, see our guide to ring placement meaning. What to Wear With It A two-finger ring stands out on its own, so you don't need much other jewelry. Keep things simple by wearing just a few thin rings or a delicate bracelet in the same metal. You can also mix gold and silver if you like.  How to Size a Two-Finger Ring and Make Sure It Fits Sizing a regular ring is simple because you only need to measure one finger. Sizing a two-finger ring is trickier because it needs to fit two fingers comfortably without making it hard to move your hand. How to Measure Two Fingers Measure both fingers separately: Wrap a thin strip of paper or string around the base of each finger. Mark where it meets, then measure the length in millimeters. Measure more than once: Your fingers can change size throughout the day, so measure them three or four times to get a better idea of your size. Choose a slightly bigger size if you're between sizes: A ring that's too tight can feel uncomfortable, especially if it has wide bands. Check the space between your fingers: See how far apart your fingers sit naturally. Make sure the ring's bands are spaced properly, and the connecting part doesn't stop your fingers from moving comfortably. Check the seller's sizing instructions: Some two-finger rings need two different sizes. Others are designed to fit a particular finger on each side. Confirm these details before ordering. For help with ring sizes and conversions, see our ring size guide. The Comfort Test A two-finger ring can make it harder to move two fingers separately. How much it affects movement depends on the ring's design, so it's important to check that it feels comfortable before buying. If possible, wear it around the house and see if you can: Bend both fingers into a fist and straighten them again. Hold a pen, phone, or mug comfortably. Type on a keyboard or phone. Wash and dry your hands easily. Put your hand in your pocket and take it out without the ring getting caught. Wear the ring without it pinching the skin between your fingers. When Your Fingers Are Different Large knuckles: Measure both the base of your finger and your knuckle. Choose a size that fits comfortably over your knuckle without being too loose at the base. Fingers that change size: Your fingers can swell or shrink depending on the temperature and time of day. Measure them when your hands are at a normal temperature. Two fingers with different sizes: If one finger is bigger than the other, a connected ring might not fit both properly. Choose a design that can be sized for each finger separately, or wear two separate rings that look like one. Resizing the ring: Ask a jeweler if the ring can be resized before you buy it. Connected rings can be harder to resize than regular rings, and some cannot be resized at all. Is a Two-Finger Ring Right for You? Go for it if you like bold jewelry, can wear it on your less-used hand, and find it comfortable. Try it first if you type a lot, lift things often, wear a wedding ring on that hand, or plan to buy it online without a clear return policy. Skip it for now if your work or hobbies require your fingers to move freely, such as playing an instrument or typing quickly.  Try wearing one for a few hours before deciding. If you're buying one as a gift and don't know the person's finger sizes, choose an adjustable design. If you're unsure which ring to buy, start by choosing a style you like, then decide which two fingers to wear it on. Make sure it fits comfortably before thinking about the price. How to Care for a Two-Finger Ring Taking care of your two-finger ring is simple. Follow these tips to keep it looking good: Remove your ring before showering, applying lotion, exercising, or washing dishes. Keep it flat in a jewelry box to prevent scratches and tangles. Use a soft toothbrush, a little dish soap, and a gentle touch. Avoid scrubbing too hard, especially if the ring is gold-plated, as this can damage the finish. Ultrasonic cleaners may damage some rings, especially those with delicate stones or settings. Ask your jeweler which cleaning method is safe. If the connecting part becomes loose or bent, take it to a jeweler for repair instead of trying to fix it yourself. For more tips, see our guide on how to care for your rings.

Diamond chains have become the piece of jewelry that men, especially, are going crazy for. And we keep seeing the same pattern. Someone spots their favorite celebrity in a chain covered end to end in diamonds, walks into the nearest jeweler, and buys the first diamond chain that looks close enough.  What they never hear about are the hidden choices that could have made it fit their taste, suit the way they dress, and quite possibly cost a good deal less than what they paid. What we mean is that a diamond chain is not just a snake of diamonds wrapped around your neck.  It is a necklace or chain with diamonds set into its links or along its strand, usually in gold or platinum, and it comes in three main kinds: tennis chains (a continuous line of stones), diamond Cuban or iced-out chains (stones set across heavy links), and station or pendant chains (a few diamonds spaced along the chain). The phrase also covers a huge range. On one major US marketplace, men’s diamond necklaces run from about $11 to over $20,000. This guide is about what sits inside that gap, so you can buy the chain that suits you, not the one your favorite celebrity wears. Which Type of Diamond Chain Is Right for You? Decide which of the three you’re shopping for before you look at a single stone. They look different, they wear differently, and their cost is different. Tennis chain Diamond Cuban / iced-out Station / fine chain What it looks like A continuous chain of matching gemstones Thick interlocking links with gemstones across the surface A thin chain with a few diamonds spaced along it Usually worn as A classic everyday piece or a gift A statement piece, most often by men A daily, layering piece Where the money goes Number and quality of gemstones Gemstones plus a lot of gold Design and metal; the diamonds are small Diamond tennis chains A tennis necklace name actually came from a tennis bracelet. A tennis chain is sold by total carat weight, the combined weight of every stone on it, and a necklace needs far more stones than a bracelet. That is why a tennis necklace typically costs two to three times as much as the same style in a bracelet.  You can learn more about it in our diamond tennis necklace guide. Diamond Cuban and iced-out chains A Cuban link chain is made of thick, oval-shaped links that fit closely together and lie flat. “Iced out” means the chain is covered in diamonds or other stones to make it sparkle. Together, they create the bold, flashy chain often worn by celebrities. In a diamond Cuban chain, the chain’s width and weight matter a lot. Much of its price comes from the gold itself, not just the diamonds. So, when comparing two Cuban or iced-out chains, you need to look at both the gold and the diamonds to understand which one is worth the money. Diamond station and fine chains Diamond station necklace style is simple and subtle. It usually has a thin chain with a few small diamonds spaced along it, or a diamond built into the chain as a pendant. Some jewelers call this a “diamond chain.” It’s perfect for everyday wear because it’s light and easy to style. Since the diamonds are small, the chain’s design and metal make the biggest difference in how it looks. What Does “Diamond” Mean in a Chain Listing? Diamond Cuban chains can cost anywhere from $11 to over $20,000, but the word “diamond” doesn’t always mean the same thing. At the cheaper end, you might find a 12 mm silver Cuban chain for around $11. At the expensive end, a 22-inch chain made of 14k white gold with real diamonds totaling 17.75 carats can cost over $20,500. The middle price range is where you need to be careful. For example, one diamond chain costs around $1,300 and is advertised as having 8.50 carats of “moissanite diamonds.” It has G - H color and VVS1 clarity ratings, and is made of 14k yellow gold over sterling silver. Here’s what that actually means: Moissanite: A gemstone that looks like a diamond but is not a real diamond. VVS1 clarity: A diamond clarity grade used for diamonds, but here it describes the moissanite. 14k gold over sterling silver: The chain is made of silver with a layer of gold on top. It is not solid 14k gold. The lesson you can learn: Always read the full product description. A chain advertised as a “diamond Cuban link” might have real diamonds, moissanite, or just gold plating over silver. These materials have very different values. Natural and lab-grown: both are diamond Lab-grown diamonds are becoming popular in all kinds of jewelry, and there’s a good reason for that. They are real diamonds with the same chemical and physical structure as natural diamonds, but they can cost 30–50% less. So, why are they cheaper? We explain the reasons in our detailed lab-grown vs. natural diamond guide. If you’re shopping for a diamond chain and the listing says it has lab-grown diamonds, don’t assume they’re fake. They are real diamonds, just made in a lab instead of forming naturally in the Earth. The problem is when a seller doesn’t tell you the diamonds are lab-grown but charges you the price of natural diamonds. Always ask your jeweler whether the diamonds are natural or lab-grown before buying. Moissanite and Cubic Zirconia: Not Real Diamonds You might also come across moissanite or cubic zirconia (CZ). These are different gemstones with different chemical structures and properties. They usually cost much less than diamonds and can offer plenty of sparkle. If you want a sparkly chain at a lower price, these can be good options. However, they are not diamonds, and their resale value is generally much lower than that of natural diamonds. For everyday wear, both can be suitable choices. Still confused about which one to choose? Check out our detailed guide comparing diamonds and moissanite. A quick decoder for listing language What the listing says What it usually means What to ask “Diamond” on its own Natural, lab-grown, or a loose use of the word Which one, and can I see that in writing? “Lab-grown diamond” A real diamond grown in a lab Is there a report from an independent lab? “Lab-created” with no gem named Could be lab-grown diamond, moissanite or cubic zirconia Which gemstone, exactly? “Moissanite” or “CZ” A different gemstone, not diamond Does the price match that? “Diamond-cut” A textured finish on the metal; no diamonds Are there any actual diamonds on this? “Diamond accent” A small number of small diamonds How many stones, and what total carat weight? “VVS” or “VS” Clarity grades from the diamond scale Who graded it, and does it apply to every stone? “Gold plated,” “gold over silver,” “vermeil” A gold layer over another metal Is the chain itself solid gold? “14k” or “10k” alone The purity of the gold Is it solid or hollow, and how many grams? How to Read a Diamond Chain’s Specs When buying a diamond chain, two things matter most: total carat weight and diamond quality. But these can be confusing if you don’t know what they mean. Total Carat Weight: What Does It Really Mean? A carat measures a diamond’s weight. One carat equals 200 milligrams. For a ring, carat weight usually refers to the weight of its main diamond. But for a chain, total carat weight means the combined weight of all the diamonds on it. For example, a 5-carat diamond chain doesn’t have one big 5-carat diamond. It has many smaller diamonds that add up to 5 carats. A 1-carat tennis necklace might have 30 - 50 tiny diamonds, while a 10-carat necklace usually has bigger stones. This is why two chains with the same total carat weight can look very different. A chain with many tiny diamonds gives a more sparkly look, while one with fewer, larger diamonds looks bolder. So, don’t look at carat weight alone. Ask the seller how many diamonds the chain has and how big each diamond is. For Cuban chains, the wider and longer the chain, the more stones it usually needs to cover the surface. Which of the 4Cs matter on a chain You’ve probably heard of the 4Cs of diamonds: cut, color, clarity, and carat weight. The 4Cs help you understand a diamond’s quality, but they work a little differently when buying a diamond chain. A chain has many small diamonds, so sellers usually describe them using a range, such as “G - H color and VS clarity,” instead of grading every stone separately. With such small diamonds, it’s hard to notice the difference between nearby clarity grades just by looking at them. So, what matters more in a diamond chain is whether the diamonds look alike and sparkle evenly. If the diamonds have different colors, the chain may look uneven under the light. And if they’re poorly cut, they may look dull instead of sparkly, even if their grades sound good. So, what should you focus on? Choose a chain with well-cut diamonds that match in color and sparkle. You usually don’t need to pay extra for the highest clarity grade to get a great-looking chain. What a certificate does, and doesn’t, tell you GIA and IGI are two well-known diamond grading labs. You’ll often hear their names when shopping for diamond chains. A report from an independent lab is generally more reliable than a certificate made by the seller. But you still need to check what the report actually covers. For example, a report for one diamond only tells you about that specific stone. For a diamond chain, check whether the report covers every diamond, the entire chain, or just the seller’s own description. Metal, Settings, and Build Quality: What Makes a Diamond Chain Last? For a diamond chain, diamonds may be the main attraction, but the metal and how the chain is made determine how well it holds up those diamonds over time. Good construction helps the chain stay in good shape and keeps the diamonds securely in place. The first thing to create a secure and strong chain is the karat. Gold Karat  Karat tells you how much pure gold is in a piece of jewelry out of 24 parts. Pure gold is 24k, but it’s too soft for everyday wear, so it’s mixed with other metals to make it stronger. Here’s how much pure gold different karat levels contain: 10k gold: About 41.7% pure gold. 14k gold: About 58.3% pure gold. 18k gold: About 75% pure gold. 24k gold: Almost 100% pure gold. For example, a 60-gram chain made of 14k gold contains about 35 grams of pure gold. The same weight in 10k gold contains about 25 grams, while 18k gold contains about 45 grams. The higher the gold karat, the more pure gold the chain contains, which usually means a higher price. This makes a big difference in heavy Cuban chains because they use a lot of metal. Karat What to expect 10k Hardest-wearing and lowest price, with a paler color 14k A common middle ground: richer color than 10k, tougher than 18k 18k Warmest color, softer and more easily scratched, higher price Gold Color If gold karat tells you how much pure gold is in a chain, gold color decides how the chain looks with its diamonds. The three most common gold colors are yellow gold, white gold, and rose gold. Each gives a diamond chain a different style, especially with Cuban link chains that contain a lot of gold. Yellow gold: Gives the chain a classic, traditional look. White gold: Gives it a clean, modern look. Rose gold: Gives it a stylish, slightly pink look. Gold also comes in other colors, each with its own unique appearance. Explore our detailed guide to the different types of gold colors to learn more. How the stones are held Setting How it holds the stones Upside Downside Pavé Many tiny stones set into small beads of metal Maximum coverage and sparkle The tiny beads can wear, and stones can loosen over the years Prong Small metal claws grip each stone Lets in more light The claws can snag on clothing Bezel A metal rim wraps each stone Most protected, smooth to the touch Shows slightly less of the stone If you’ll wear the chain daily, or it will rub on collars and jackets, a bezel or a well-made pavé holds up better than exposed prongs. A chain for dinners and weekends can afford the extra sparkle. Links, joins and clasps A diamond chain is only as strong as its weakest point, and that is rarely the stones. It is the clasp and the joins between links. On anything heavy, look for a secure clasp with a safety latch and ask how the links are joined. A seller who makes chains can answer in a sentence. How Much Does a Diamond Chain Cost? What Drives the Price There is a short list of things that decide the price of a diamond necklace, and once you know them, you can read any listing. Total carat weight of the diamonds The type of diamonds used: natural or lab-grown Stone quality and matching The gold karat Setting work. Paperwork, warranty, and the seller’s margin. How to Choose Length and Width Most chain sizing guides are made for plain gold chains. Diamond chains can fit a little differently, so use these tips as a starting point. To find your chain size, wrap a string or soft measuring tape around your neck where you want the chain to sit. You can also measure a chain you already own and like, from one end to the other, including the clasp. Add 2 - 3 inches to your neck measurement for a comfortable fit. You want Start around A collarbone length for everyday wear (men) 20 inches, the most common men’s length A layered look 22 to 24 inches A longer, relaxed drape Up to about 26 inches A close fit (women) 16 to 18 inches Chain Width Matters Too Most men’s chains are around 2–6 mm wide, while thicker chains can reach 10 mm. Diamond Cuban chains are often wider, with sizes like 10 mm, 12 mm, and 15 mm. The wider the chain, the heavier and stiffer it usually feels. A thick chain can sit close to your neck like a collar, so you may want to choose a longer length for a more comfortable fit. For example, an 18-inch chain that’s 12 mm wide will feel very different from an 18-inch chain that’s only 3 mm wide. Check out our how to choose men’s necklace guide for more detail regarding length and sizing. How to Check a Diamond Chain Is What the Seller Says Test Works on What it catches What it misses Fog test Mounted or loose stones Glass, cubic zirconia, most imitations Moissanite and lab-grown diamond Water (sinking) test Loose stones only Very lightweight fakes Cubic zirconia, moissanite Newspaper (dot) test Loose stones only Glass, cubic zirconia, crystal Moissanite Basic thermal tester Mounted or loose stones Many imitations Moissanite, which conducts heat much like diamond Read in detail to know if the material used in your diamond necklace is real or not: How To Tell If a Diamond Is Real How To Tell If Gold Is Real The eight-point check before you pay What are the stones?

Including what happens if a stone comes loose. Independent verification. Will they let you have it checked by an independent gemologist or appraiser? When to get it professionally tested If the chain is a significant purchase, or the answers to the checklist are vague, take it to an independent gemologist or appraiser with proper testing equipment. Test before you agree to the price, not after. Wearing and Caring for a Diamond Chain A diamond chain is made to be worn, but taking good care of it will help it last longer. Put it on after applying lotion or perfume, and take it off before sleeping, working out, swimming, or using a hot tub. Keep it away from bleach and strong cleaning products, as these can damage the gold and the chain’s links. How to Clean a Diamond Chain at Home Soak it: Put the chain in warm water with a few drops of mild dish soap for 15–20 minutes. Brush gently: Use a soft toothbrush to clean around and behind the diamonds. Rinse it: Wash off the soap with clean, warm water. Dry it: Gently pat it dry with a soft cloth that won’t leave lint behind. If your chain has lots of small diamonds set closely together, ask your jeweler before using an ultrasonic cleaner, as it may loosen some stones. Check Your Chain Regularly Every few months, check your chain in good light. Look for loose or missing diamonds, stones that look tilted, or a clasp that is difficult to open and close. If you hear a slight rattling sound, have a jeweler check it. It’s also a good idea to have your jeweler inspect the chain once a year to make sure everything is secure.  Which Diamond Chain Should You Actually Buy?
