Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque green color with a shimmering metallic luster known as aventurescence, trigonal crystal system, and no distinct cleavage.
Formation & geological history
Forms within metamorphic environments, particularly quartz veins and pegmatites, where chromium-rich fuchsite mica flakes become trapped during quartz crystallization.
Uses & applications
Widely used for ornamental carvings, polished cabochons in jewelry, and popular among mineral collectors.
Geological facts
The shimmering effect is caused by tiny plate-like mineral inclusions reflecting light, a phenomenon called aventurescence.
Field identification & locations
Easily identified by its characteristic green sparkle and high quartz hardness; commonly sourced from Brazil, India, and Russia, fitting well with South American pegmatite deposits.
