The four Cs are the four characteristics traditionally used to determine the quality and value of a diamond carat, cut, clarity, and color. The characteristics of a diamond are graded and categorized by the diamond industry to establish its retail value. Quality diamonds are often graded by a qualified expert and carry a certificate of authentication. This is typically through a third-party lab such as GIA, EGL or AGS.
