Diamond carat weight measures how much a diamond weighs. The metric carat is the basic unit of measurement for the weight of diamonds.

The diamond colour evaluation of most gem-quality diamonds is based on the absence of colour. The colour scale ranges from D to Z, with grade D diamonds appearing icy white and Z diamonds with a pale yellow hue.

Cut is the feature that determines the brilliance of a diamond. In the case of diamond, the term “cut” includes two concepts: the shape of the diamond and the quality of its proportions and finish. Therefore, we can talk about the type and quality of the cut.

A variety of internal features called “inclusions” and external features called “blemishes” can result from the creation of a diamond. Its clarity is defined by the presence or absence of visible inclusions or imperfections.
