Diamond Shapes and Cuts
Learning about diamond shapes and cuts can be confusing. “Shape” refers to the outline of a diamond (such as pear, round, or oval). “Cut” has multiple meanings. When talking about the 4Cs, “cut” refers to the way the diamond is cut to let light through the crown (a well-cut diamond isn’t cut too deep or too shallow). When talking about the look of the diamond, “cut” refers to the way the cut of the diamond impacts the arrangement of the diamond’s facets (such as cushion cut or emerald cut).
To reduce confusion, we use “shape” to refer to the look of the diamond (whether that’s an actual outline such as an oval or the arrangement of the diamond’s facets such as an emerald).

Round Brilliant
The classic diamond shape with 58 facets to maximize light return and sparkle.
Princess
Combines the sparkle of a round diamond with the contemporary shape of an emerald cut diamond.
Emerald
A rectangular shape with cut corners known as a step cut (because its concentric, broad, flat planes resemble stair steps).
Pear
Combines the cut characteristics of both the round brilliant and marquise cut diamonds for an elegant “teardrop” shape.
Oval
A fairly modern cut from 1957, the oval’s graceful and proportional shape makes it a popular choice for engagement rings
Cushion
Combines the cut characteristics of both round and oval diamonds and works well with vintage styles. Its rounded corners and larger facets increase the diamond’s brilliance.
Marquise
This elongated shape has been around for centuries and symbolizes love that lasts the ages.
Radiant
Reminiscent of an emerald cut diamond, but with 70-75 facets for a more brilliant return of light.
