Physical properties
Hardness: 7 on Mohs scale. Color: Green (ranging from pale to dark green). Luster: Vitreous to greasy. Crystal System: Trigonal. Cleavage: None. Specific Gravity: 2.65.
Formation & geological history
Formed through the hydrothermal alteration of quartz veins, where tiny flakes of green mica (fuchsite) become trapped inside, giving it a shimmering effect known as aventurescence.
Uses & applications
Widely used in tumbled stones, gemstone jewelry, carvings, and as a decorative mineral specimen favored by collectors and crystal practitioners.
Geological facts
The name aventurine derives from the Italian 'avventura,' meaning 'by chance,' referring to the accidental discovery of aventurine glass in the 18th century, which was subsequently named after the natural mineral.
Field identification & locations
Easily identified by its characteristic green color combined with a metallic glittering or shimmering appearance (aventurescence) caused by mineral inclusions. Commonly found in India, Brazil, Russia, and the United States.
