Moissanite in fancy shapes
Moissanite in fancy shapes by Charles & Colvard

What exactly is moissanite? Is it a lab-grown or synthetic diamond substitute? Not at all.

Moissanite is the name given to a naturally occurring and lab-grown mineral made up of silicon carbide. Its occurrence in nature is extremely rare and has only been found in upper mantle rock and meteorites. Discoveries have shown moissanite occurs naturally as inclusions in diamonds, xenoliths, kimberlite, and lamproite.

Today—because of its rarity—moissanite is lab grown with minimal environmental impact. Because of its durability, moissanite can be found in a variety of cuts, which give jewelry designers a plethora of options for settings.
