Diamond Shape: The Top 10 Guide to Selecting the Ideal Cut

While diamond shape is one of the most important factors in the diamond’s appearance, some cuts are more exceptional than others. The masterfully designed Esperanza diamond is a case in point. Although diamond size often gets the headlines, let’s take a look at the top 10 most popular diamond cuts in the world.

Diamond Shape: The Top 10

1. Round Cut

The round cut is the most in-demand diamond shape. In fact, 75% of all engagement rings are set with a round cut diamond. Round cut diamonds are typically a brilliant cut with 58 facets that enhance the sparkle. They are also noted for their romantic Hearts & Arrows pattern. However they are expensive to produce, as a lot of the rough diamond is lost when the stone is cut. But if you’re looking for a timeless classic style, the round cut diamond is for you.

2. Oval Cut

The oval cut is a modified brilliant round cut diamond shape. If you are dazzled by the shine in a round cut, but are looking for a slightly larger diamond, this is your diamond. Its elongated shape makes it appear larger than its actual size. And although less expensive than a round cut diamond, it is somewhat less popular.

3. Marquise Cut

The marquise cut is a football-shaped diamond. It is a modified brilliant cut with 56 facets, elongated and tapered at both ends to create the look of a larger diamond. Its unique shape is not a popular engagement ring style, which makes it a good choice for the buyer with less-standard taste. The marquise cut is perfect for a solitaire setting but also looks beautiful with accent diamonds.

4. Pear Cut

The pear cut is a combination of an oval cut and a marquise cut. The diamond shape is round at the top and tapers to a point resembling a pear or a teardrop. This cut does not work well with smaller diamonds as it demands perfect symmetry to create true light performance beauty. For the full effect, the stone should be a larger carat weight. Although it makes a gorgeous statement ring, the pear cut is most often used in pendants or earrings.

5. Heart Cut

The heart is the eternal symbol of love and the heart cut diamond evokes that feeling. It is far from the traditional style of diamond shape for an engagement ring. The cut is only effectively viewable on a larger carat weight, such as at least 1 carat. In fact, since the cut makes the diamond appear smaller than it actually is, the heart cut works best on larger stones. It is a difficult shape to cut, so take extra care when looking for flaws and birthmarks.

6. Princess Cut

The princess cut is a square diamond shape. Like the round cut diamond, the princess cut is elegant, traditional and feminine, making it a highly popular choice for engagement rings. The princess cut is also cheaper than a round cut diamond, due to the fact that two equally sized princess cut diamonds can be cut from the same rough stone.

7. Cushion Cut

The cushion cut gets its name from its unique diamond shape. It is a square cut with rounded edges that create a look resembling a pillow or cushion. The large facets allow for more shine.

8. Radiant Cut

The radiant cut is a square or rectangle diamond shape with the brilliance of a round cut diamond and the elegance of a princess cut. The pattern is a modified square shape that maximizes color refraction – hence the ‘radiance’ and shine that gives the cut its name.

9. Emerald Cut

The emerald cut diamond is very popular amongst celebrities but less so with the general buying market. It has a rectangular diamond shape with cut corners and a large flat table that enhances the visibility of the diamond’s birthmarks, its inclusions and flaws. It is a very elaborate and decorative cut with a beautiful sparkle.

10. Asscher Cut

The Asscher cut is an Art Deco style created in 1902 by the Asscher Diamond Company in Holland. It is a square cut with large facets, high crown and a smaller table, so it is more brilliant than the emerald cut. However, birthmarks are relatively visible with the Asscher cut, which means you’ll need a higher quality cut. And that generally translates to higher price.


With so many beautiful diamond shape and cut options available, the choice is a hard one. The first step for diamond ring buyers is to understand the personality and aesthetic preferences of the wearer. Next, take into account the physical features of the hand and ring finger. Different diamond shapes are more suitable and flattering, depending on the size of the hand, length and width of the fingers. Don’t forget all the other purchase variables, including budget, diamond size, metal color and setting. Then, you can narrow down the field to discover your ideal diamond shape choice.
