WHAT IS A MOISSANITE?

Mineral moissanite was discovered by 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.[5][6] Artificial silicon carbide had been synthesized in the lab by Edward G. Acheson just two years before Moissan's discovery.[7]

The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life. The discovery in the Canyon Diablo meteoriteand other places was challenged for a long time as carborundum contamination had occurred from man-made abrasive tools.[8]
