Home » Charles & Colvard Moissanite - Loose Gemstones

Moissanite by Charles & Colvard

Moissanite is an extremely rare mineral that was discovered in a meteor crater by French chemist Henri Moissan in 1893. Today, all moissanite available in the marketplace is synthesized in laboratories, and North Carolina-based Charles & Colvard is known for creating the world's most stunning moissanite stone. Forever Brilliant ® Moissanite is up to four shades whiter (equivalent to a diamond with H-I color) than conventional moissanite (Forever Classic™), and Forever One ™ Moissanite gemstones are magnificently colorless (equivalent to D-F color diamonds). Both varieties are 10% more brilliant than a diamond and have a hardness of 9.25 on the Mohs scale of hardness, comparable to a diamond's score of 10 (the hardest possible).

Moissanite Size Guide

When comparing the carat weight of a moissanite gemstone to a diamond of the same size, the moissanite will weigh less. Therefore, we prefer to use the millimeter (mm) measurements when referring to our moissanite sizes. Here are some handy charts to compare moissanite and diamond sizes to their equivalent carat weights.
