Physical properties

Formation & geological history

Formed in metamorphic rocks and magmatic environments where tectonic pressure and heat allow for the recrystallization of quartz containing mineral inclusions. Found in high-grade metamorphic rocks.

Uses & applications

Mainly used in jewelry, ornamental carvings, figurines, and widely used as a 'healing stone' in crystal therapy and spiritual practices.

Geological facts

The name 'Aventurine' comes from the Italian 'a ventura,' meaning 'by chance,' originally referring to the accidental discovery of aventurine glass in the 18th century.

Field identification & locations

Identify in the field by its distinct green color and 'aventurescence,' which is a metallic glitter caused by tiny mica inclusions. Commonly found in India, Brazil, and parts of Russia.
