Moissanite
webcentivewebcentive - home
Moissanite is lab-grown silicon carbide used as a diamond alternative. It is very hard and shows more "fire" (rainbow sparkle) than diamond, but it is doubly refractive and is not a diamond; natural gem-quality moissanite has not been found, so jewelry moissanite is lab-made. Under the FTC Jewelry Guides, sellers must not call it a diamond. Ask for the stone's color and size in writing and get the return policy before you buy. Sellers below are commercial.
