A carat is a unit of mass used to measure the weight of a diamond or gemstone.

Diamond Carat Size Chart

To determine a diamond or gemstone’s weight, each stone is weighed individually. One carat is equivalent to 200 milligrams, or 0.2 grams.

It is important to bear in mind that, while carat weight can influence the price of a diamond, no two diamonds of the same weight will be worth the same. Each diamond is valued by taking into account the 4 C’s: Carat, Cut, Color and Clarity.

Which carat weight should I choose?

When deciding on a diamond engagement ring, most couples will focus on the carat weight of the diamond. A 1-carat diamond is one of the most popular choices, however, if you are on a budget look for diamonds that fall just under these popular carat weights. For example, instead of choosing a 1-carat diamond, go for a 0.90-carat. They look almost the same but the price will be significantly lower!
