The carat measurement describes
the diamond's weight. As the weight increases, the value of the diamond
increases (assuming all other characteristics are equal). Diamonds
are weighed according to the metric carat system, in which one metric
carat equals 0.2 grams. One carat can also be expressed as 100 points.
Therefore, one-half carat is referred to as fifty points. The weight
of the diamond, combined with its dimensions, is important in identifying
the value of a diamond.
