Rhinestones are typically sold in bulk, with quantities often expressed in gross.
One gross equals 144 stones.This measurement standard dates back to early trade practices and is still used for ease and consistency in the industry.
The term 'gross' derives from the French word 'grosse douzaine,' meaning 'large dozen,' which signifies twelve dozen or 144 pieces. This was particularly useful for merchants who dealt in bulk goods, allowing them to easily calculate large quantities.
The use of 'gross' as a measurement unit dates back to a time when trade and commerce required easy-to-understand and universally accepted units for counting various items, including gemstones and pearls.
