Physical properties
Hardness: 7 on the Mohs scale; Color: Dull to forest green; Luster: Vitreous to waxy; Structure: Hexagonal/Trigonal; Specific Gravity: 2.64-2.69; Features platy inclusions that create 'aventurescence'.
Formation & geological history
Formed in magmatic and metamorphic environments where quartz crystallizes and silica-rich solutions incorporate mica or fuchsite inclusions. Found primarily in metamorphic schists and quartzites.
Uses & applications
Used in jewelry, decorative carvings, statues, and metaphysical/spiritual practices as a 'stone of opportunity'. Also used in ornamental construction.
Geological facts
The name 'Aventurine' comes from the Italian 'a ventura', meaning 'by chance', originally referring to accidental manufacturing of Italian glass with copper filings. This natural mineral resembles that glass.
Field identification & locations
Identify by its characteristic shimmery effect called aventurescence. Commonly found in India, Brazil, and Russia. Collectors look for even coloration and a strong shimmer.
