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.
