FAQs About Half Carat Diamonds

A carat is a unit of measurement that refers to the weight of a diamond. The carat of the diamond affects the price of the diamond more than any other of the 4Cs.

The cost of any diamond is based on a number of factors, including carat, cut, colour, and clarity. Depending on these factors, a half-carat diamond value can range anywhere from a few hundred dollars to a few thousand dollars.

Because a carat is a measurement of weight, not size, a half-carat diamond size varies based on the cut of the diamond. For a round cut, a 0.5 carat diamond averages 5.1mm in diameter.

The two best ways to make a diamond appear larger than its actual carat weight are with the diamond’s cut and setting. A thin, delicate setting will make the diamond seem larger in perspective. Featuring the diamond in a halo setting is another way to make a diamond appear larger.
