Diamond Carat (Weight)

“Carat” is a unit of measurement used to measure the weight of diamonds and other gemstones. One carat is equal to 0.2 grams. For reference that is about the same weight as a small paperclip. One carat is divided into 100 points, similar to how a dollar is divided into 100 pennies. For example, 50-point diamond weighs 0.50 carats. In the diamond industry, weight is often measured to the hundred thousandths of a carat and rounded to a hundredth of a carat. Diamond weights greater than one carat are expressed in carats and decimals. (For instance, a 1.08 ct. stone would be described as “one point oh eight carats,” or “one oh eight.”). If two diamond have the same weight (carat), they can have vastly different value based on the evaluation of the other aspects of the 4C's - clarity, colour and cut. 

*Please note that there is a difference between Carat and Karat.
