Physical properties

Hardness: 7 Mohs; Color: Pale to dark green with 'aventurescence' (shimmer); Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None; Specific gravity: 2.64-2.69

Formation & geological history

Formed in magmatic and metamorphic environments where silica-rich fluids crystallize. The green color and shimmer are caused by inclusions of green chrome-mica known as Fuchsite.

Uses & applications

Commonly used in jewelry (beads, cabochons), ornamental carvings, figurines, and as a popular stone for crystal healing and metaphysical collections.

Geological facts

The name 'aventurine' comes from the Italian 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass or 'goldstone'. Green aventurine is known as the 'Stone of Opportunity'.

Field identification & locations

Field identification involves checking for the characteristic metallic shimmer when rotated under light and its inability to be scratched by a steel knife. Commonly found in India, Brazil, Russia, and Madagascar.
