Diamond Carat

Often mistaken with size, carat it is actually a measure of weight.
One carat is equivalent to 200 milligrams. One carat can also be divided into 100 ‘points’. A .75 carat diamond is the same as a 75-point or 3/4 carat diamond.
Since larger diamonds are found less frequently in nature, a single 1-carat diamond will cost more than two 1/2-carat diamonds, assuming the colour, clarity and cut are the same.
Cut and mounting can make a diamond appear larger or smaller than its actual weight. A diamond’s setting should always optimise its beauty.
