Diamonds and other gemstones are weighed in metric carats: one carat is equal to 0.2 grams, about the same weight as a paperclip. (Donât confuse carat with karat, as in â18K gold,â which refers to gold purity.) Just as a dollar is divided into 100 pennies, a carat is divided into 100 points. For example, a 50-point diamond weighs 0.50 carats. But two diamonds of equal weight can have very different values depending on the other members of the Four Câs: clarity, color and cut. The majority of diamonds used in fine jewelry weigh one carat or less. Because even a fraction of a carat can make a considerable difference in cost, precision is crucial.
