Physical properties
Hardness: 7 Mohs; Color: Forest green to light green; Luster: Vitreous to waxy; Texture: Granular with shimmering platelets (aventurescence); Cleavage: None
Formation & geological history
Formed in metamorphic environments where quartz-rich sediments are subjected to heat and pressure, allowing mica platelets (Fuchsite) to become trapped within the quartz matrix.
Uses & applications
Used extensively for carvings, cabochons, beads for jewelry, and as a popular pocket stone for collectors.
Geological facts
The name 'Aventurine' comes from the Italian 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass.
Field identification & locations
Identified by its signature green color and tiny shimmering scales of mica when rotated under light. Commonly found in India, Brazil, and Russia.
