The crystalline structure is held together with strong covalent bonding similar to diamonds,that allows moissanite to withstand high pressures up to 52.1 gigapascals.Colours vary widely and are graded in the F-G-H-I-J-K range on the diamond color grading scale.

Introduction of 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.The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life. The discovery in the Canyon Diablo meteorite and other places was challenged for a long time as carborundum contamination from human abrasive tools.
