Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque green color with a shimmering metallic luster (aventurescence), trigonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and metamorphic environments through the inclusion of green chromium-rich mica flakes within cooling quartz.
Uses & applications
Commonly used in crystal healing, ornamental carvings, polished tumbled stones, and occasionally low-cost jewelry.
Geological facts
The shimmering optical effect is known as 'aventurescence,' which was named after the stone rather than vice versa, originating from an accidental glass-making discovery in Italy.
Field identification & locations
Easily identified in the field by its distinct green sparkle and quartz hardness; commonly sourced from India, Brazil, Russia, and South Africa.
