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 Diamonds

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

As the name suggests, radiant diamonds tend to emit a beautiful, memorable glow.

Oval Diamonds

Cut with the same number of facets as a round diamond, an oval shape emits nearly the same level of brilliance and fire. Due to its elongated shape, the oval cut can appear larger than a round diamond of equal carat (weight).
