Step One: Select Shape

Diamonds are available in a variety of popular shapes. You should not confuse "cut" or "cut grade" with shape. The "cut" or "cut grade" is how well-cut a diamond is, and the diamond's shape is the shape or form it was cut into. Different shapes are preferred for various types of jewelry. Round Brilliant shaped diamonds are the most popular, especially for engagement or wedding rings.
