Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Pale to deep green; Luster: Vitreous to waxy; Crystal Structure: Trigonal (Hexagonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.64-2.69.

Formation & geological history

Forms in metamorphic rocks like phyllites and schists where quartz recrystallizes in the presence of mica minerals such as fuchsite. Common in Precambrian or younger metamorphic belts.

Uses & applications

Primarily used for ornamental carvings, jewelry (beads, cabochons), landscaping stones, and as a popular collectible 'healing' stone.

Geological facts

The name 'Aventurine' comes 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

Identified by its 'aventurescence,' which is a shimmering effect caused by platy mineral inclusions. Commonly found in India, Brazil, and Russia. Field identification relies on hardness and the characteristic green plucky sparkles.
