Formation & geological history

Formed in metamorphic rocks (phyllites and schists) and occasionally in igneous rocks. The green color is caused by platy inclusions of Chromium-rich mica known as Fuchsite.

Uses & applications

Used primarily in jewelry (beads, cabochons), ornamental carvings, landscaping stones, and as a popular stone for chakra and meditation practices.

Geological facts

The name comes from the Italian 'a ventura', meaning 'by chance', originally referring to an 18th-century accidental discovery of aventurine glass. Natural aventurine is often confused with jade.

Field identification & locations

Identify by its characteristic metallic shimmering effect called 'aventurescence'. Commonly found in India, Brazil, Russia, and Tanzania. It is harder than glass but brittle.
