History & Origin
The carat has its origins in the carob seeds, which were historically used as a balance scale for weighing gemstones since they have a relatively consistent weight. This practice dates back to ancient civilizations, where traders relied on these seeds to measure precious stones. The use of carob seeds as a standard weight led to the definition of the carat as a specific weight measurement.
Etymology: The term 'carat' derives from the Arabic word 'qīrāṭ,' which refers to the carob seed. This seed was traditionally used in commerce as a unit of weight for precious stones.
