The Discovery of Moissanite Moissanite was first discovered in 1893 by French chemist Henri Moissan while examining a meteorite crater in Canyon Diablo, Arizona. Initially thought to be diamonds, the tiny crystals were later identified as silicon carbide (SiC). This unique composition sets moissanite apart from diamonds, which are made purely of carbon. Due to its rarity in nature, nearly all moissanite available today is lab-created, making it a sustainable and accessible gemstone.
