Physical properties
Hardness of 9-9.5 on the Mohs scale, metallic luster, iridescent rainbow colors, and hexagonal or rhombohedral crystal structures.
Formation & geological history
Primarily synthesized industrially via the Acheson graphite process, though extremely rare natural grains occur in meteorite impacts and kimberlites.
Uses & applications
Used widely as an abrasive in sandpaper, in cutting wheels, high-performance ceramics, and semiconductor applications.
Geological facts
Also known as moissanite, synthetic specimens often display stunning rainbow iridescence due to a thin silicon dioxide surface layer.
Field identification & locations
Easily identified by its extreme hardness, light weight, metallic sheen, and colorful iridescence; commonly found in mineral shops as synthetic clusters.
