Carat is a measurement of a diamond’s weight, and is reflective of the size of the stone.
Two diamonds of the same carat weight can appear different sizes depending on the shape and how well the diamond is cut, but generally speaking, carat is a good indicator of a diamond's size.
Referred to in short-form as ‘ct’, carat is a unit of measurement used for diamonds and other precious gemstones, like rubies, sapphires and emeralds, equating to 0.20g.
