Physical properties
Hardness: 6.5-7 (Mohs scale); Color: Green; Luster: Vitreous to waxy; Crystal structure: Trigonal; Cleavage: None; Specific gravity: 2.64-2.69
Formation & geological history
Formed in metamorphic rocks and magmatic environments where mica or other inclusions are present during the crystallization of quartz. Inclusions of fuchsite mica give green aventurine its characteristic color and aventurescence.
Uses & applications
Primarily used for ornamental jewelry, tumbled stones, figurines, and as a decorative stone in landscape and interior design. Popular in the metaphysical community.
Geological facts
The name 'Aventurine' comes from the Italian 'a ventura,' meaning 'by chance.' This refers to the accidental discovery of aventurine glass (goldstone) in the 18th century, which looks similar to the natural mineral.
Field identification & locations
Identify by its characteristic 'aventurescence,' a shimmering or glistening effect caused by platy inclusions. It is commonly found in India, Brazil, Russia, and Austria. Unlike dyed quartz, its color is usually throughout the stone.
