CaratThe weight of a Carat (200 milligrams), standard unit of measurement for gemstones, is based on the weight of the carob seed, which was once used as a weighing standard by jewelers in Africa and the Middle East. The word "Carat" itself is believed to be derived from an Arabic word meaning "bean" or "seed."
