Physical properties
Hardness: 7 Mohs scale; Color: Green with aventurescence; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None; Specific gravity: 2.64-2.69
Formation & geological history
Formed primarily in metamorphic environments such as schists or quartzites. The green color and shimmering effect are caused by platy inclusions of chromium-rich mica known as fuchsite.
Uses & applications
Used extensively in jewelry, ornamental carvings, beads, tumbled stones, and as a healing stone in metaphysical practices.
Geological facts
Aventurine gets its name from the Italian 'a ventura', meaning 'by chance', originally referring to accidental discovery of aventurine glass in the 18th century before the mineral was named.
Field identification & locations
Identified by its grainy texture as a quartzite variety and its characteristic shimmering 'aventurescence'. It is commonly found in India, Brazil, and Russia.
