• 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.
