Physical properties

Formation & geological history

Formed in metamorphic rocks and magmatic environments. The green color comes from inclusions of Fuchsite mica that align during the cooling or pressure phase of the quartz formation. Common in quartzites.

Uses & applications

Widely used for ornamental carvings, jewelry (cabochons and beads), landscaping, and as a popular 'healing crystal' in metaphysical practices.

Geological facts

The name 'Aventurine' is derived from the Italian 'a ventura', meaning 'by chance', referring to the accidental discovery of aventurine glass or 'goldstone' in the 18th century, which looks similar.

Field identification & locations

Identify by its green color combined with a grainy quartz texture and a subtle internal sparkle (aventurescence) when turned under light. Most commonly found in India, Brazil, and Russia.
