About Moissanite

Moissanite is a lab-created gemstone made from silicon carbide, valued for its brilliance and durability. It was first discovered in a meteorite crater in 1893 and later recreated in laboratories as an ethical and conflict-free alternative to mined diamonds. Its refractive index, 2.65 to 2.69 compared to diamond's 2.42, gives it more fire and sparkle. With a hardness of 9.25 on the Mohs scale, it resists scratches and wear with daily use.
