Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Formed in metamorphic environments, particularly in quartz veins, pegmatites, and regional metamorphic rocks, often containing chromium-rich mica inclusions.
Uses & applications
Used in gemstone jewelry, carvings, tumbling, decorative objects, and favored in crystal healing.
Geological facts
The green color and shimmering effect (aventurescence) are caused by tiny flat flakes of fuchsite, a chromium-rich variety of muscovite mica.
Field identification & locations
Commonly found in India, Brazil, Russia, and Austria. Identified by its characteristic green color and sparkling metallic sheen.
