Physical properties
Hardness: 7 Mohs; Color: Light to dark green; Luster: Vitreous to waxy; Crystal Structure: Hexagonal/Trigonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.64-2.69. It is characterized by 'aventurescence' (a metallic glitter).
Formation & geological history
Forms primarily in metamorphic rocks like quartzite where mica inclusions (Fuchsite) provide the green coloration. It is formed under high temperature and pressure during regional metamorphism.
Uses & applications
Widely used for ornamental carvings, tumble stones, decorative figurines, and jewelry beads and cabochons. It is also used in metaphysical practices.
Geological facts
The name 'Aventurine' comes from the Italian 'a ventura,' meaning 'by chance,' and was originally applied to a man-made glass accidentally created in Venice. This mineral is often mistaken for jade.
Field identification & locations
Identify in the field by its green color and the presence of tiny, shimmering mica flakes inside. It is commonly found in India, Brazil, Russia, and Austria. Collectors should look for even color distribution and strong shimmer.
