Carat refers to the weight of a diamond. The higher the carat weight, the more valuable it is (other factors being equal). A carat weighs 200 milligrams and is divided into 100 points. A .5 carat diamond is the same as a 1/2 carat diamond which is the same as a 50-point diamond.

Over a carat, diamond weights are usually expressed in carats and decimals. A 1.06 ct. stone, for example, would be described as "one point oh six carats," or "one oh six."
