Evaluating Diamonds
In 1931 Robert M. Shipley founded the Gemological Institute of America to study and assess gemstones. He introduced the 4 C’s, a system for evaluating the quality and value of diamonds on color, clarity, carat weight and cut. Cut is the arrangement of facets on the stone and should not be confused with shape, the geometric form of the stone. It is very important to have a well-cut diamond because it is the faceting that makes the light refract, creating sparkle.
