Cimes — 4

The first C, Carat, refers to the weight of a diamond. One carat is equivalent to 0.2 grams or 200 milligrams. Diamond weights are usually measured in decimal points, such as 0.5 carats or 1.2 carats. Larger diamonds are generally more valuable, but the price per carat increases exponentially with the diamond's weight. This means that a 2-carat diamond is not twice as valuable as a 1-carat diamond, but rather four to six times more valuable.
