What is moissanite?

Moissanite is a rare, naturally occurring silicon carbide gemstone that was discovered in 1893 by French scientist Henri Moissan, hence the name. Moissan found the gemstone within a fallen meteor located in Canyon Diablo, Arizona, initially mistaking it for diamonds. Because of the extreme rarity of this gemstone, the vast majority of moissanite on the market today is lab created and therefore ethical and conflict-free. Moissanite is near-colorless and has a similar refractive index to a diamond, but has more colors and fire making quick flashes of rainbow color when moving the stone around. Though moissanite looks similar to diamond and the DIA deems it the closest diamond imitation, it is its own unique gem with unique chemical and optical properties and is not a synthetic diamond but it is a great diamond alternative.
