Carat is derived from Greek work keration the name of the carob tree which produces pods with seeds.
Once dried these seeds become black and hard. The ancient merchants then used these seeds for
weighing pearls, diamonds and other precious stones.
Carat weight was only standardized in the early 19th century officially adopting the metric carat.
One carat = 0,2 gram or 200 milligram.
