Meet Marquise Cut Diamonds

The marquise cut is a classic and historic diamond shape that captures hearts thanks to its whimsical shape that resembles a smile. Although we don't blame you if you see something else. Marquise cut stones are also called boat-shaped, football-shaped and eye-shaped diamonds, or the navette. None of these are incorrect; in fact, the “navette” cut diamond, which translates from the French language to “little ship,” is often considered similar in shape to all these things. Despite their dramatic look, marquise diamond cuts are rarely seen in engagement rings; but for some non-traditional brides, that only increases their appeal.

What you need to know about the marquise diamond cut

We'll get more into who created this captivating diamond shape later, but they did start quite the trend. The shape was invented specifically for the diamond, but the marquise cut trend eventually spread to sapphires, emeralds, and other precious stones. Although the marquise never hits the popularity of other diamond shapes in engagement rings, it's the perfect stone for couples looking for a unique ring to celebrate their love and devotion.

We've all seen marquise stones in rings, but maybe you didn't realize they weren't engagement rings. Traditionally this stone has been set in more cocktail and right-hand rings than their engagement cousins, but that has been changing. There's good reason to choose this stone, too. It has almost 60 facets within its rounded central shape and sharply pointed ends, which means it truly delivers on the drama. You'll get plenty of sparkle from the marquise cut stones but also style. This shape is particularly beloved for its unique ability to make fingers look thinner and longer.

The visual appeal of marquise cut diamonds

The marquise is a variant of round and pear shaped diamonds and, like the oval, is a perfect complement to long, slender fingers. But, as we mentioned, it can also create this affect thanks to its shape. The long-thin body and pointed ends draws the eye up, so your fingers will look longer and thinner when you're sporting this stone in your engagement ring. But there are benefits for your ring as well as your hand.

This diamond shape's elongated body can make its appearance larger than its actual carat weight. So you'll be able to buy the same carat weight and have your stone look bigger than someone who purchases, say, a round brilliant diamond. For brides-to-be who prioritize the size of their rings, this is a major draw of the unique marquise cut. But size isn't the only concern if you're looking to commit to this diamond shape in your engagement ring.

While choosing your diamond shape and engagement ring setting should ultimately come down to your personal choice, each diamond shape shines in particular settings. Marquise cut diamonds have inherent drama; the pointed ends make for an interesting and dramatic finish to the soft rounded center. Because of this, the marquise shape looks especially graceful in classic, solitaire and halo settings. After all, who wants to distract attention away from such a unique and captivating stone? But that doesn't mean you're limited in your engagement ring options if you decide this is the diamond for you.

It's common to have marquise shapes paired with other gemstones to create unique and interesting ring styles. (You might want to check out some sapphire and diamond engagement rings for some gorgeous inspiration.) But another way you can personalize your marquise cut engagement ring is through the stone's ratio. The suggested length to width ratio ranges from 1.75 to 2.25. However, see if you prefer a longer or shorter marquise diamond to pick a shape that is visually appealing for you. A longer marquise diamond can create the illusion of a larger looking diamond as the carat weight is spread over a larger area. But you might prefer the look of a shorter marquise cut diamond, and that's OK too. The most important thing is that you love your diamond.

Marquise diamond cut origin

The marquise diamond origin began hundreds of years ago. The name refers to a rank in the royal family between count and duke, given by birthright, not by marriage or appointing. The name came about as it was a reflection of the rank of courtiers who were able to wear these diamonds, though now they're known by several names. The original version of this diamond cut was created in the 18th century by a jeweler hired by King Louis XV. He paid the jeweler to create a uniquely shaped diamond, comparable to the mouth of his beloved mistress.

Marquise cut pricing

Marquise cut diamonds, like other fancy shapes, have a discount in pricing when compared to round cut diamonds of the same carat weight. Round diamonds have greater rough diamond wastage, whereas marquise diamonds use the long shape of rough diamonds very well. These diamonds do a good job of distributing carat weight in the tips of the diamond, which allows the diamond to look larger than other shapes such as princess or cushion. Therefore, a 1.00 ct marquise diamond cut will be about 10.5 x 5 mm versus a 1.00 ct round cut diamond, which will be about 6.4 mm.

It is important to find well cut marquise shapes that don’t have light leakage from the bow tie effect, though. (This is when light is not reflected as sparkle back from the center of the diamond. You can find out more about diamond bow ties here.) Luckily, this is pretty easy to avoid at Four Mine. You can visually see the bow tie effect when looking at the diamond videos available on our loose diamonds catalog. Also feel free to chat with a diamond consultant about any diamond to learn if there is a bow-tie effect.

Marquise diamond cut guide

This diamond shape offers unique beauty, but there are a couple things you need to keep in mind when shopping for a loose diamond. We've already mentioned the length to width ratio. To help you along the way while shopping, we've included a table about the ratio below, which includes depth and length to width ratio combinations for marquise cuts.

But another important consideration when selecting a marquise cut is the color. Marquise diamonds tend to show color more, specifically in the ends, because they have less depth in the tips. A G color marquise will look closer to an H color diamond. Consider opting for a stone one color grade higher with marquise shapes, when compared to round shaped diamonds. This will ensure that you get less faint yellow coloring in the dramatic ends of your beloved stone.

As with any other diamond, you'll also need to be sure that the diamond looks symmetrical. But an asymmetrical marquise cut can be easier to spot than, say, a cushion that's off because of the ends. Make sure the two pointed ends align with each other. If possible, opt for a diamond with excellent or very good symmetry. In terms of clarity, avoid a diamond that has visible inclusions in the central portion. By selecting a diamond that has inclusions on the pointed ends, they may be covered by the prongs when the diamond is placed in a diamond setting. A higher clarity grade becomes increasingly important as one is opting for a larger carat size. When choosing a ring setting, ensure that the marquise diamond is always set in a way where the points are protected to prevent them from chipping or cracking. Four Mine takes extra care to design and craft marquise rings so that the diamond is fully protected within the setting.
