The Four C's of Diamonds

Carat - Clarity - Color - Cut


Carat weight is the unit of measurement used to describe the weight of diamonds. One carat is equal to 0.2 grams, or 0.007 ounces


Diamond clarity relates to the visibility of flaws, blemishes or inclusions in or on the stone. The fewer inclusions, the more brilliant the stone.


Diamond color is graded on a scale from “D” (near colorless) to “Z” (light – canary yellow). After Z, the stones fall into the fancy color categories.


Diamonds may be cut in several different shapes and fashions to enhance their radiance or to take advantage of the best attributes of that particular stone.
