Carat refers to the weight of a diamond; this is one of the major contributors to the price at which a diamond is sold. The term originates from the word “carob” seed, which was the original term, used by diamond merchants and is not to be confused with “karat” which refers to gold’s purity. A carat equates to 0.2 grams today, similar to the weight of a raindrop or paper clip. Diamonds of higher carat weights demand a higher price because they can be few and far between; however it’s important to keep in mind that carat size doesn’t necessarily reflect the physical size of the diamond and that two diamonds of the same carat weight can have different costs based on the quality of other characteristics such as cut, clarity and colour. Carats are usually divided into points, with 100 points equalling 1 carat. Diamond prices are often based off a price-per-carat system.
