Carat is a term used to describe the weight of a diamond or other gemstone. It is a measurement of mass equal to 0.2 grams, or 200 milligrams. A single carat is divided into 100 points, so a diamond of 75 points could be described as a 0.75 carat diamond. Carat weight is often used to determine the size of a gemstone, and is one of the four C’s (Cut, Color, Clarity, and Carat) used to assess the value of a diamond. The larger the carat weight of a diamond, the larger the physical size and the higher the value of the diamond.
