Physical properties
Hardness: 7 Mohs scale. Color: Dark forest green. Luster: Vitreous to waxy. Crystal Structure: Trigonal/Microcrystalline. Features prominent conchoidal fracture and a glistening aventurescence.
Formation & geological history
Formed in metamorphic or igneous environments where quartz crystallizes along with chromium-rich fuchsite mica, giving it a rich green color.
Uses & applications
Used widely in lapidary arts, jewelry, decorative carvings, cabochons, and as a popular tumbled stone for collectors.
Geological facts
The name Aventurine derives from the Italian 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass (goldstone) in the 18th century.
Field identification & locations
Identify by its waxy to vitreous luster, distinct conchoidal fracture, hard quartz composition (scratches glass), and fine sparkling mica inclusions. Commonly sourced from India, Brazil, and Russia.
