The term carat is often associated with the cut of a diamond, whereas in reality, the carat is the unit of measurement that applies to the weight of the diamond.
One carat is equal to 0.20 grams, or about a quarter of the weight of a dry grape. The probable origin of this measurement is the carob seed, which served as a unit of measurement since ancient times.
The diamond industry now uses electronic scales to weigh diamonds. The word carob is at the origin of the word carat, which we are using today. Carat weight is not visible to the naked eye. Several factors influence the weight of a stone, such as its shape.
