"In 1907, the Fourth General Conference on Weights and Measures - an international organization responsible for metric measurement standardization consisting today of more than 70 member nations - adopted the carat as the official metric measurement for gemstone weights."
This standard was adopted, because the previous standard -- carob seeds -- were not predictably standard or uniform.
