Physical properties

Hardness: 6.5-7 (Mohs); Color: Pale to medium green; Luster: Vitreous to waxy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (Conchoidal fracture); Specific Gravity: 2.64-2.69

Formation & geological history

Formed in metamorphic rocks (schists and quartzites) through the recrystallization of quartz grains under high pressure and temperature. The green color is derived from inclusions of chromium-rich mica known as fuchsite.

Uses & applications

Commonly used for lapidary work, jewelry (beads, cabochons), ornamental carvings, and widely sold as a healing stone in the metaphysical community.

Geological facts

Aventurine is famous for its 'aventurescence,' a shimmering effect caused by light reflecting off tiny platelets of mica within the stone. Historically, it has been confused with jade.

Field identification & locations

Identify in the field by its speckled green appearance and shimmering internal reflections. It is commonly found in India (the largest producer), Brazil, Russia, and Austria.
