Mineral moissanite was discovered by French Chemist Ferdinand Frédéric Henri Moissan while examining rock samples from a meteor crater located in Canyon Diablo, Arizona, in 1893.

At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as silicon carbide.

The mineral form of silicon carbide was named Moissanite in honor of Henri Moissan later on in his life.
