Physical properties
Hardness of 7 on the Mohs scale, green color due to fuchsite mica flecks, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed through the hydrothermal alteration of quartz veins or in metamorphic environments where quartz-rich rocks undergo regional metamorphism with chromium-bearing micas.
Uses & applications
Commonly used in wire-wrapped jewelry, carvings, tumbled stones, and decorative objects.
Geological facts
Aventurine displays a glistening effect called aventurescence, caused by the reflection of light from small flat inclusions like fuchsite within the quartz.
Field identification & locations
Identified by its translucent to opaque green body color interspersed with tiny shimmering metallic or sparkly specks. Found globally, notably in India, Brazil, Russia, and Austria.
