The amount of gold in an article of jewelry is defined by the ‘carat’ or ‘karat’ scale. The word is derived from the Greek keration and Italian carato meaning the fruit of the carob tree whose pods were once used for weights in early bazaars. Pure gold is 24 carat; other alloys being a percentage of 24. Divide marked karat by 24 to get the % of fineness.
(example: 10 karat gold 24 = 41.6% pure gold)
