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.
