Physical properties
Hardness of 7 on the Mohs scale, pale to dark green color due to chromium-rich mica inclusions, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, and specific gravity of 2.64-2.69.
Formation & geological history
Formed through regional metamorphism or hydrothermal processes where quartz-rich solutions incorporate tiny flakes of fuchsite or other green minerals during crystallization.
Uses & applications
Widely used in ornamental carvings, tumbled stones, beaded jewelry, and crystal healing practices.
Geological facts
Aventurines often display a shimmering or glistening effect called aventurescence, caused by the reflection of light from tiny flat inclusions within the stone.
Field identification & locations
Identified by its translucent green color and distinctive metallic shimmer (aturescence). Commonly found in India, Brazil, Russia, and Austria.
