A diamond''s weight is the simplest characteristic to measure, and from the earliest times has been used to appraise the value of a diamond. The carat is a unit of weight, which derives from the carob seed. The pods of a carob, or locust tree, contain collegering tiny seeds, which are remarkably consistent in weight. These seeds were used by early gem traders to weigh their diamonds. A 1-carat diamond used to equal the weight of a carob seed; but in today''s terms the carat is a standard metric weight of 0.2 grams or 1/142 of a standard ounce. Each carat is divided into 100 points. So, for example, a quarter of a carat is 25 points, written as 0.25; a half a carat is 50 points written as 0.50; and so on. It is easy to weigh an un-mounted diamond, but once it is in a setting, it is only possible to estimate its weight by using special gauges and formulas. Remember, carat-weight has no bearing on a diamond''s cut, color or clarity. We have made every effort to provide you with accurate product photographs, descriptions and specifications.
