Diamond Shapes

Explore the 10 most popular diamond shapes. Each is uniquely brilliant, evoking emotion and reflecting the personality of its owner.

The simplest way to categorize a diamond is by its shape. Commonly available in 10 different options, the shape of a diamond makes the biggest impact on the appearance of an engagement ring.

The classic round diamond is the most popular shape, renowned for its ideal brilliance. All other diamond shapes are known as “fancy” shapes; these diamonds are prized for their elegance and unique facet patterns.

Buying Tip: While you’re researching diamonds, you’ll see the term “diamond shape” as well as “diamond cut”. These terms are used interchangeably: A “round cut diamond” is the same thing as a “round shaped diamond”. They both refer to the silhouette of the diamond. The diamond’s silhouette is different than its cut grade, which is one of the 4 Cs and describes its quality.

Round Diamond

Classic circle shape with maximum sparkle. With 57 to 58 facets cut to produce incredible sparkle, round shaped diamonds are truly timeless. The round shape is the first of the modern diamond cuts, and first gained popularity in the 1920s.
