What's a carat?

A carat is a unit of weight that is used to measure the mass of gem stones and pearls. 1 carat = 200mg. The word "carat" comes to English from the Greek and Arabic words for "carob seeds" Way back when, traders used carob seeds as a balance on their scales when they weighed gold.

The difference between carats and karats

“Carat” is a variation of “karat”. The “carat” refers to gem stones and is a unit of weight, “karat” refers to gold and is a unit of purity. Outside of the US and Canada, the spelling “carat” is used to refer to the purity of gold.
