Physical properties

Hardness: 7 on Mohs scale; Color: Translucent to opaque pale to dark green; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Specific gravity: ~2.65

Formation & geological history

Formed in metamorphic settings, quartzites, and pegmatites where silica-rich fluids crystallized in the presence of mica-rich fluids, imparting a distinctive green color from fuchsite (chromium-rich muscovite).

Uses & applications

Popular for lapidary work, gemstones, carved figurines, tumbled stones, jewelry, and decorative items. Widely collected as a gemstone and metaphysical crystal.

Geological facts

The name 'Aventurine' comes from the Italian word 'a ventura', which means 'by chance', referring to the chance discovery of aventurine glass (goldstone) in the 18th century.

Field identification & locations

Look for the signature platy mica inclusions that create a subtle glistening or shimmering effect called aventurescence. Commonly found in India, Brazil, Russia, and Madagascar.
