Moissanite is a rare, naturally occurring mineral also known as silicon carbide. Named after Nobel Prize-winning chemist Dr. Henri Moissan, Moissanite was first discovered in 1893 at the site of a massive meteorite strike in Arizona. Scientists in Research Triangle Park, North Carolina later developed the thermal growing process that creates silicon carbide crystals, which are fashioned into Moissanite gemstones.http://www.jiangyuanjewelry.co....m/silver-moissanite-
