Physical properties
Hardness: 7 on Mohs scale. Color: Green, ranging from pale to dark green. Luster: Vitreous to greasy. Crystal structure: Trigonal. Specific gravity: 2.65.
Formation & geological history
Formed through the hydrothermal alteration of quartz-rich rocks where chromium-rich mica (fuchsite) becomes trapped during crystal growth.
Uses & applications
Used in ornamental carvings, tumbling, jewelry, and crystal healing practices.
Geological facts
The name aventurine derives from the Italian word 'avventura', meaning 'by chance', referring to the accidental discovery of aventurine glass in the 18th century.
Field identification & locations
Identified by its characteristic translucent green color and sparkling metallic sheen caused by mineral inclusions. Commonly found in India, Brazil, Russia, and Austria.
