Diamond Shape Guide

The simplest way to categorize a diamond is by its shape. Commonly available in at least 16 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.
