Diamond cut should not be confused with shape. Shape refers to the general outward appearance of the diamond, not its reflective qualities. Brilliant Earth currently carries the following shapes:
Oval
Round
Marquise
Emerald
Cushion
Old Mine
Pear
Radiant
Princess
Asscher
Heart
Color
Color is the natural color visible in a diamond and does not change over time. Colorless diamonds allow more light to pass through than a colored diamond, releasing more sparkle and fire.
Absolutely colorless or icy white. The highest color grade—extremely rare and most expensive.
Clarity
A diamond’s clarity refers to the presence of impurities on and within the stone. When a rough stone is extracted from carbon deep beneath the earth, tiny traces of natural elements are almost always trapped inside. These elements are called flaws or inclusions because they are formed naturally and are unique to each stone.

Cut
The cut refers to the angles and proportions of a diamond. The cut of a diamond—its depth and width, and the uniformity of the facets—determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light.
Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly all light that enters the diamond.

Carat
A carat is the unit used to measure a diamond's weight. One carat equals 200 milligrams or 0.2 grams. Although carat weight and the size of a diamond are related, the carat does not directly measure diamond size.
