Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200mg. Each carat can be subdivided into 100 points. This allows very precise measurements.

We often think of a diamond’s cut as its shape, but a diamond’s cut grade is really about how well a diamond’s facets interact with light.

Color evaluation is based on the absence of color. The color scale for diamonds begins with D, representing a colorless diamond, and continues to Z.

The process of creating a diamond in nature results in internal and external characteristics called “inclusions” and “blemishes”. The clarity scale begins with flawless and ends with included.
