Diamond Size:

The carat is the unit of weight of a diamond. Carat is often confused with size even though it is actually a measure of weight. One carat equals 200 milligrams or 0.2 grams. The scale below illustrates the typical size relationship between diamonds of increasing carat weights. Remember that while the measurements below are typical, every diamond is unique.
