Diamond Carat Weights
The international standard unit of weight for diamonds is the metric carat, which is equal to .200 or 1/5 gram. For precision, a carat is subdivided into 100 points. Thus, a 1 carat diamond weighs 100 points and a 1/2 carat diamond weighs 50 points. Larger diamonds are very rare, thus adding to the mystique and allure of the gem.
Above is an example of three diamonds that all have the same carat weight, yet they all look different. This is because they have a different cut. The diamond on the left has the proper cut to allow as much light to return through the top of the diamond as possible. The diamond in the center and on the right weigh the same as the diamond on the left, yet inferior cuts make one look too small, and one look too squatty and dull. At Orin's, we rigorously examine every diamond for the optimal ratio between carat weight and cut.
