Diamond Shape

When selecting a diamond, shape is one of the most important factors to consider. The contours and outlines of a diamond have a significant impact on its appearance. The brilliant round cut diamond has long been the most popular, although many modern consumers prefer alternative shapes, including cushion, princess, and radiant, among others. At Brilliance, we offer the most popular diamond shapes in our diamond search. Below, learn more about their unique traits, aesthetic properties, and markings of quality.

Round Cut Diamonds

Round Cut Diamonds

The most commonly chosen shape, round diamonds have been researched by gemologists more than any other variation.
