* Diamond Equivalent Weight" (DEW) when exploring different carat sizes. DEW is a term used to describe the approximate size of a moissanite gemstone in comparison to a diamond of the same weight.

Moissanite has different physical properties than diamonds, which affect its density and light dispersion. As a result, moissanite gems have a different size appearance compared to diamonds of the same carat weight. To provide an easy reference for consumers, the DEW measurement allows you to understand how a moissanite gemstone compares to a diamond in terms of size.

* Carat weight (ct.) is the standard unit of measurement for gemstones, including diamonds. It refers to the weight of the stone, with one carat equaling 200 milligrams.
