The name marquise came about as it was a reflection of the rank of courtiers who were able to wear these diamonds. The marquise is a variant of round and pear shaped diamonds, and like the oval is a perfect complement to long, slender fingers. It can make fingers look thinner and longer.

It is an excellent cut to show the impression of long, slender fingers. Marquise diamonds have a ship like majestic nature. They are commonly worn in cocktail and right hand rings as well as engagement rings. As diamond rings, the marquise shape looks especially graceful in classic, soltiaire and halo settings. It is also common to have marquise shapes paired with other gemstones to create unique and interesting ring styles. The suggested length to with ratio is 1.75 to 2.25 is the ideal shape.

Marquise Diamond 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 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. It has almost 60 facets within its rounded central shape and sharply pointed ends. We’ve all seen the marquise diamond cut. Many people compare the cut to a football, a boat, or even an eye. 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. It is less common than other cuts of diamonds, especially in engagement rings. It was originally a cut specifically for diamonds, but the marquise cut trend eventually outstretched to sapphires, emeralds, and other precious stones. Marquise diamonds can be long or short. All are beautiful, so it is important to select one based on your taste.
Marquise Cut Pricing
Marquise diamond cuts, 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. Marquise 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 bow tie effect. Bow tie is when light is not reflected as sparkle back from the center of the diamond. The light leakage makes it look like a black or dark bow tie in present in the diamond. Avoid diamonds with the bow tie affect as these are less than optimal diamond cuts. You can visually see the bow tie effect when looking at the diamond videos available on Four Mine. Also feel free to chat with a diamond consultant about any diamond to learn if there is a bow-tie effect. Learn more about diamond pricing.
Additionally, It is very important to examine a diamond’s length to width ratio when considering the shape. Marquise diamonds with a ratio of 1.75 - 2.25 with be in the optimal ratio range. These possess the greatest premium in the marquise cuts. Shorter or longer marquise cut diamonds will look either a little thicker or slender and longer. This isn’t necessarily a bad thing, but merely a preference. Shorter marquise diamonds will look smaller and slender, long length to width ratios will look larger.
Marquise Diamond Cut Guide
Please see the ideal table, depth and length to width ratio combinations for marquise cuts. An important consideration when selecting a marquise cut is the color. Marquise tend to show color more than round diamonds due to less depth in the tips. A G color cushion will look closer to an H color diamond. Consider one higher color grade with marquise shapes, when compared to round shaped diamonds. When considering other factors, be sure that the diamond looks symmetrical. The two pointed ends should 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.
