Diamond carat

The international unit of measurement for diamond weight is the "carat", often abbreviated to "ct". Carat weight is one of the 4Cs of diamonds. A diamond's weight is the most easily measurable feature of the 4Cs, and carat weight is equivalent to a diamond's charisma. A diamond of the same quality, the heavier it is, the more precious it is.
