BUYER'S GUIDE TO MARQUISE CUT DIAMONDS
It all started with a brilliant smile. Louis XV of France requested that the court jewelers cut a diamond in the shape of the lips of his mistress, the Marquise de Pompadour. The resulting diamond cut is the marquise: two curved sides ending in two points. Because the shape also resembles a boat, it’s also sometimes called the navette diamond.

The History of Marquise Cut Diamonds
Whether or not the story about Louis XV and his mistress is true, the marquise cut is part of the revolution in diamond cutting in the eighteenth century, as better equipment allowed cutters to experiment with adding more facets to a wide range of brilliant cuts.
The marquise cut suited the decorative taste at the time and represented innovation. In Britain, the shape’s nautical shape found favor with the Edwardians. Sailing was a popular pastime for King Edward VII.
In America, the marquise was particularly popular in the 1950s and again in the 1970s. Jacqueline Kennedy received one from Aristotle Onassis.

How to Buy Marquise Diamonds
Here’s what you need to know about shopping for marquise diamonds. The basics of the 4Cs are the same as for round brilliant diamonds but the GIA grading reports for marquise diamonds don’t include a cut grade. That means any cut grade you see on a retailer’s website is more about marketing than science.
Because marquise cut diamonds are less common than round brilliants, many retailers won’t have any in stock. You are much better off buying fancy shapes like this online because you’ll have a much better selection in your target color, clarity and carat weight. This really helps you compare the shapes and cut qualities and pick a really beautiful diamond that’s a good value too.
It’s important to rely only on diamond grading reports from GIA or AGS, the world’s most respected diamond grading laboratories. You can’t rely on the grades from other labs to be equivalent.
The dazzling French court at Versailles sparkled with more beautiful diamonds than had ever been seen before.
But the thing we love most
about marquise-cut diamonds is that
they are relatively shallow.
about marquise-cut diamonds is that
they are relatively shallow.
Why? That means that they look larger than almost any other diamond shape. Just look at a comparison of rings set with 1.25-carat diamonds in six different shapes.
See how big the marquise looks in comparison to the round brilliant? It’s as if your diamond magically grew 20 percent in size!
And there’s one more thing we love about marquise shape diamonds. They are 30-40 percent cheaper than round brilliant diamonds of the same size and quality. So they look bigger and they cost less? How could you not love marquise cut diamonds?
Marquise Diamond vs Oval Diamond
vs Pear Shaped Diamond
vs Pear Shaped Diamond
The two diamond shapes that are most similar to a marquise cut are the oval diamond and the pear shaped diamond.
The oval shape diamond is much more classic and traditional than the marquise cut. It has a similar elongated silhouette and shallow depth so it also looks relatively large on your finger. It is more subtle than the marquise.
Pear shaped diamonds are as unconventional as the marquise cut, with the added drama of asymmetry.
All three are much larger in appearance than the round brilliant and less per carat for the same
quality. The marquise cut is the most affordable
of the three.

Any prong setting needs v-shaped prongs over the points.

When you are shopping for marquise diamonds,
the first factor that you’ll want to consider is the
length to width ratio: a comparison of how
round or elongated the marquise shape is.
A ratio of 1.5 would be fatter and a ratio of 2.5 would be skinnier. Which you like best is a matter of personal taste but most people prefer something in the middle.
Here’s an example of a distracting bow tie.
No matter which shape appeals to you most, there is one important factor to consider in the cut. Almost every marquise cut diamond has an optical effect called the “bow tie”: a dark pattern of light across the center of the diamond. It’s usually the reflection of your head (or the camera in photographs.) The effect can be really obvious in some diamonds and less so in others.
Although your marquise shaped diamond will have a bow-tie in some form, it’s important to choose a marquise that sparkles with brilliance across the whole diamond, even in the bow tie area.
