Carat

"The larger a diamond is, the more rare it is"

Carat is a weight measurement of diamonds and precious stones. Large diamonds are relatively rare in nature making them more valuable. What makes a bigger diamond so desirable is that it shows off a stone's color and cut, therefore its brilliance, to it's best advantage. Diamonds are measured in carat weight and each carat is equal to 100 points. A .50 carat diamond is the same as a 50-point diamond or a 1/2-carat diamond. While larger diamonds are highly prized, diamonds of equal size may vary widely in value and brilliance, depending on their qualities of clarity, cut and color.
