Physical properties
Hardness: 7 (Mohs scale); Color: Green with visible shimmering inclusions; Luster: Vitreous to waxy; Crystal Structure: Hexagonal (trigonal); Cleavage: None
Formation & geological history
Formed in magmatic and metamorphic environments where quartz crystals contain platy inclusions of mica (fuchsite) during crystallization, creating the aventurescent effect.
Uses & applications
Commonly used in jewelry (beads, cabochons), metaphysical practices, and ornamental carvings.
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
Identified by its signature 'aventurescence' (metallic glitter). Found commonly in India, Brazil, and Russia. Collectors look for uniform color and strong glitter.
