Physical properties
Hardness: 6.5-7 (Mohs); Color: Green; Luster: Vitreous to waxy; Crystal Structure: Trigonal (microcrystalline); Cleavage: None; Specific Gravity: 2.64-2.69
Formation & geological history
Formed in metamorphic environments where quartz-rich sediments are subjected to high pressure and temperature, incorporating mica like green fuchsite during crystallization.
Uses & applications
Commonly used for lapidary work, jewelry (beads, cabochons), home decor, and as a popular 'luck' stone in crystal healing communities.
Geological facts
Its name comes from the Italian word 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass (goldstone) in the 18th century.
Field identification & locations
Identify by its 'aventurescence', a shimmering or glistening effect caused by platy mineral inclusions. Commonly found in India, Brazil, and Russia.
