1. Cut
The first C in evaluating a diamond, whether natural or lab-grown, is cut. This refers to the way the diamond is fashioned, impacting its brilliance and sparkle. A well-cut diamond maximizes light return, resulting in a dazzling play of light and fire. Round brilliant cuts are the most popular choice for their exceptional sparkle, but there are many other beautiful shapes available, such as oval, cushion, and radiant. Regardless of the chosen shape, a well-cut diamond will showcase its brilliance and beauty to the fullest.
