Physical properties
Hardness of 7 on the Mohs scale, pale to dark green color, translucent to opaque, vitreous to greasy luster, trigonal crystal system, specific gravity around 2.65.
Formation & geological history
Formed in metamorphic environments, often as hydrothermal veins or within quartzites and schists where quartz recrystallizes with platy mica mineral inclusions.
Uses & applications
Widely used in tumbled stones, carved figurines, jewelry, and ornamental items.
Geological facts
The distinctive green shimmer or sparkle in green aventurine is caused by tiny mica or fuchsite flakes trapped inside the quartz matrix, a phenomenon known as aventurescence.
Field identification & locations
Found globally including in India, Brazil, Russia, and the United States. Easily identifiable by its characteristic green color combined with a glistening or metallic sheen.
