Diamonds are sold by the carat. which is actually a unit of weight, though most think of a carat in terms of size. a carat is equal to exactly 0.2 grams . Carat weight is unrelated to the similar sounding karat, which refers to gold's purity.

At that point, other criteria will take on more importance. Most women can tell you the carat weight and shape of their ideal diamond, and most men can tell you the price.
