    When buying a diamond, most people look at carat, color, clarity, and price. But with a marquise diamond, there’s more to consider. Two diamonds with the same ratings can look very different. One might look long and elegant, while the other looks shorter and wider. Some sparkle beautifully from end to end, while others have a dark shadow across the middle.

    A marquise cut engagement ring is a great choice if you want a long, pointed diamond that stands out and looks different from a traditional ring.

    Before buying one, check four things: the diamond’s shape and length, the dark shadow in the middle (called a bow-tie), whether both pointed ends look even and are protected, and whether the setting keeps the diamond secure. This guide will help you check each of these things so you can choose the right ring.

    Is a Marquise Cut Engagement Ring Right for You?

    Before choosing a marquise diamond, think about what you like about its shape and what you need to take care of. It looks beautiful and unique, but it also has a few things to consider.

    What You'll Love

    • Looks bigger: Its long shape makes the diamond look larger and covers more of your finger.

    • Unique style: It's less common than round or oval diamonds, so your ring can stand out.

    • Versatile design: It looks beautiful in both vintage and modern settings.

    • Longer-looking fingers: Its elongated shape can make your fingers look longer and slimmer.

    What to Keep in Mind

    • Pointed ends: The tips can chip if they get hit, so they need proper protection.

    • Dark shadow: Some marquise diamonds have a dark shadow across the middle, called a bow-tie. Choose one where this shadow isn't too noticeable.

    • Can catch on things: If the pointed ends aren't protected, they can snag on clothes or hair.

    • Wedding band fit: Some wedding bands may not sit flat against a marquise ring.

    A marquise engagement ring is a good choice if you want something unique with a long, elegant shape and don't mind taking a little extra care of it.

    If you work with your hands a lot or want a ring that's easy to maintain, a round or oval diamond may be a better option. These shapes can also make it easier to find a wedding band that fits neatly against your ring.

    What Is a Marquise Cut Diamond?

    A marquise cut diamond is a long, oval-like diamond with curved sides and two pointed ends. Its shape looks a little like a boat or an eye. It's designed to reflect light and sparkle while making the diamond look longer and larger.

    Here are four important terms to know when shopping for a marquise diamond:

    • Points: The two sharp ends of the diamond.

    • Belly: The widest part in the middle of the diamond.

    • Length: The measurement from one pointed end to the other.

    • Width: The measurement across the widest part of the diamond.

    The name marquise comes from French history, and the shape is often linked to French royalty. Some stories say it was designed to resemble a smile. However, when buying a marquise diamond, its shape, sparkle, and quality matter more than its history.

    How a Marquise Looks on Your Finger

    A marquise diamond is usually worn with its long side running along your finger. Its shape can make your finger look longer and slimmer. There are two main ways to set a marquise diamond:

    • North-South: The diamond sits lengthwise along your finger. This is the classic style and can make your fingers look longer.

    • East-West: The diamond sits sideways across your finger. This gives the ring a more modern look and makes the stone appear wider.

    With an east-west setting, the pointed ends face the sides of your fingers, so they may bump into nearby fingers or catch on gloves more easily. That's why protecting the tips is especially important.

    Choosing the Right Length-to-Width Ratio

    The length-to-width ratio determines whether a marquise diamond looks short and wide or long and slim. You calculate it by dividing the diamond’s length by its width. For example, a diamond that is 10 mm long and 5 mm wide has a ratio of 2:1.

    According to the Gemological Institute of America (GIA), many marquise diamonds have ratios between 1.6:1 and 2.2:1. A ratio of around 2:1 is a popular choice because it gives the diamond a balanced, classic look. Here’s how different ratios affect the diamond’s appearance:

    Length-to-width ratio

    How it looks

    Best for

    1.6:1–1.8:1

    Shorter and wider

    A bold look

    1.85:1–2.1:1

    Balanced and classic

    A traditional look

    2.2:1 and above

    Longer and slimmer

    A more dramatic look

    Choose a ratio based on the look you prefer. A lower ratio gives you a wider diamond, while a higher ratio makes it look longer and slimmer.

    One more thing to consider: If you choose a halo setting (a ring of small diamonds around the main stone), your marquise diamond may look wider. Choosing a slightly longer diamond can help maintain the slim look you want.

    The Bow-Tie Effect: What's Normal and What to Avoid

    When you look at a marquise diamond from the top, you may notice a dark shadow across the middle. This is called the bow-tie effect because it looks like a bow tie. It often happens when the diamond's bottom part is cut too shallow or too deep. 

    You don't need to avoid every diamond with a bow-tie effect. A slight shadow is normal, and a diamond with no bow-tie at all may look dull or lack sparkle. The key is to avoid a diamond with a large, dark shadow that takes away its sparkle.

    How to check the bow-tie effect:

    • A good sign: The shadow is light, changes as the diamond moves, and sometimes disappears at different angles.

    • A warning sign: The shadow stays dark and visible in the middle, even when the diamond is tilted.

    How to Check a Marquise Diamond's Quality Without a GIA Cut Grade

    GIA gives round diamonds an overall cut grade, but it doesn't give the same grade to marquise diamonds or other fancy shapes. However, its report still includes polish and symmetry grades, which show how well the diamond's surface is finished and how evenly it's shaped. Since there isn't an overall cut grade, you'll need to check a few things yourself:

    1. Check the shape

    2. Check the bow-tie effect.

    3. Check the symmetry.

    4. Check the polish and symmetry grades

    5. Check the pointed ends.

    After these checks, consider the diamond's color, clarity, and carat weight, just as you would with any other diamond.

    Best Settings for a Marquise Engagement Ring

    A marquise diamond setting has two main jobs: make the diamond look beautiful and protect its pointed ends. The more the setting covers the tips, the better they are protected, but you may see slightly less of the diamond. Here are some popular secure settings to consider:

    Setting

    How it protects the diamond

    Look and benefits

    Solitaire with V-prongs

    V-shaped prongs cover both pointed ends.

    A simple look that shows off most of the diamond. The prongs need regular checks.

    Bezel or half-bezel

    Metal surrounds all or part of the diamond, helping protect the tips.

    A modern style that offers good protection but covers more of the diamond's edges.

    Halo

    Small diamonds surround the main stone. The pointed ends still need proper protection.

    Adds extra sparkle and makes the center diamond look bigger and wider.

    Hidden halo

    Small diamonds sit underneath the main stone. The tips still need protective prongs.

    Adds sparkle from the side without changing the diamond's look from the top very much.

    Three-stone

    Smaller diamonds sit on either side of the marquise. The center stone's tips still need protection.

    A classic style that gives the ring a balanced look.

    Metal and Diamond Type: Two Things to Consider

    Choosing the Right Metal

    The metal you choose can change how your marquise diamond looks. White gold and platinum give the ring a clean, modern look and make a colorless diamond stand out. Yellow gold and rose gold add warmth and give the ring a more classic or vintage feel.

    The metal also helps hold the diamond securely and protect its pointed ends. Read our guide to platinum vs. gold to learn more about the differences.

    Natural vs. Lab-Grown Diamonds

    Lab-grown diamonds are real diamonds with the same chemical makeup as natural diamonds. The main difference is how they're made: natural diamonds form underground, while lab-grown diamonds are created in a laboratory. The biggest difference for most buyers is the price, as lab-grown diamonds usually cost less than natural diamonds. Learn more about how lab-grown diamonds are made.

    How Much Does a Marquise Engagement Ring Cost?

    The price of a marquise engagement ring depends on a few things:

    • Carat weight: Larger diamonds usually cost more than smaller ones. The price can increase even more as the diamond's weight goes up.

    • Quality: The diamond's color, clarity, polish, and symmetry affect its price and appearance.

    • Natural or lab-grown: Lab-grown diamonds usually cost less than natural diamonds of similar quality and size.

    • Setting and metal: A ring with extra diamonds, such as a halo or pavé setting, may cost more. Platinum settings also generally cost more than gold ones.

    Marquise diamonds can cost less than round diamonds of similar quality, but prices vary between sellers. To compare prices fairly, look at diamonds with similar carat weights, quality grades, and grading reports.

    Tip: Set your budget before you start shopping. Decide how much you want to spend on the diamond and how much to keep for the ring setting. This helps you avoid spending too much on the diamond and having too little left for the setting you want.

    Pairing a Marquise Ring With a Wedding Band

    Choosing a wedding band for a marquise engagement ring can be a little tricky. A regular straight band may not sit flat against the engagement ring because of the diamond's pointed ends. This can leave a gap between the two rings. Here are three ways to solve this:

    • Curved band: A slightly curved ring that fits around the marquise diamond.

    • Notched band: A ring with a small cut-out that makes room for the diamond's pointed end.

    • Gap style: The two rings sit slightly apart, creating a modern look.

    The best option depends on how you want your rings to fit together. It's a good idea to choose your wedding band style while shopping for your engagement ring to avoid problems later.

    Marquise vs. Oval vs. Pear: A Quick Comparison

    If you're choosing between marquise, oval, and pear-shaped diamonds, the main differences are their shapes and pointed ends. Each has a different look, so the best choice depends on your style and how much protection the diamond needs.

    A long, unique look

    A teardrop shape

    An elongated look with no pointed tips

    All three shapes can look beautiful, but each has its own advantages. If you love the long look of a marquise diamond but worry about its pointed ends, an oval is a good alternative because it has no sharp tips. A pear-shaped diamond is another option if you like the teardrop look and want only one pointed end to protect.
