Physical properties
Hardness of 7 on the Mohs scale, pale to dark green color with a shimmering or glistening effect (aventurescence) caused by mineral inclusions, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, and specific gravity around 2.65.
Formation & geological history
Forms primarily in metamorphic environments or hydrothermal veins, often as a quartzite variety where quartz grains are intergrown with tiny flakes of green mica (fuchsite).
Uses & applications
Widely used in ornamental carvings, polished stones, tumbled stones, jewelry, and crystal healing.
Geological facts
The shimmering effect, known as aventurescence, gets its name from the Italian word 'avventura', meaning 'by chance', which refers to the accidental discovery of aventurine glass in the 18th century.
Field identification & locations
Easily identified by its characteristic pale-to-medium green color combined with a metallic sparkle. Found worldwide, with significant deposits in India, Brazil, Russia, and Austria.
