Physical properties

Hardness: 7 on Mohs scale; Color: Pale to medium green; Luster: Vitreous to waxy; Crystal Structure: Trigonal (often found in massive form); Cleavage: None; Specific Gravity: 2.64-2.69

Formation & geological history

Formed through metamorphic processes in quartzites where mineral inclusions like chromiferous mica (fuchsite) crystallize within the quartz during high-pressure formation.

Uses & applications

Used extensively in jewelry, lapidary carvings, decorative crystal points, and as a popular stone for collectors and metaphysical practitioners.

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 characteristic 'aventurescence,' a shimmering or glistening effect caused by platy mineral inclusions. Commonly found in India, Brazil, and Russia. Look for the sparkly inclusions under light.
