Physical properties

Hardness: 7 on Mohs scale; Color: Forest green to pale green; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal (microcrystalline); Cleavage: None; Specific Gravity: 2.64-2.69; Features 'aventurescence' (a shimmering effect).

Formation & geological history

Formed in metamorphic rocks and certain igneous environments where silica-rich fluids crystallize. The green color and shimmer are caused by platy inclusions of green chrome-mica called fuchsite.

Uses & applications

Predominantly used for jewelry, cabochons, tumbled stones, ornamental carvings, and 'healing' crystal collections.

Geological facts

Aventurine is often called the 'Stone of Opportunity' and is frequently mistaken for jade, though it is harder and has a distinct internal shimmer. The name comes from the Italian 'a ventura,' meaning 'by chance.'

Field identification & locations

Identify in the field by its hardness (scratches glass), green color, and the presence of tiny glittering specks of mica within the stone. Found commonly in India, Brazil, and Russia.
