The 4C's : Carat Weight

Carat Weight

This is the weight of the diamond. There are 100 points in one metric carat and each diamond is weighed to the nearest 100th. ie: a three quarter carat diamond is .75ct. As larger diamonds are extremely rare the price per carat will increase at a greater rate. Therefore a 2.00ct diamond is not 2 times the price of a one carat diamond but will cost 3 to 4 times more.
