Physical properties

Hardness: 6.5-7 Mohs. Color: Sea green to forest green. Luster: Vitreous to waxy with 'aventurescence' (shimmer). Crystal structure: Hexagonal (trigonal). Cleavage: None. Specific Gravity: 2.64-2.69.

Formation & geological history

Formed primarily as a metamorphic rock, adventure quartz is created when quartz-rich sedimentary or igneous rocks undergo high pressure and heat, incorporating mica inclusions that provide the green hue.

Uses & applications

Widely used for ornamental carvings, figurines, jewelry (cabochons and beads), and as a popular stone for decorative landscaping and metaphysical collecting.

Geological facts

The name 'Aventurine' comes from the Italian word 'a ventura', meaning 'by chance', originally referring to an 18th-century accidental discovery of Italian glass that looked like the natural stone.

Field identification & locations

Identify by its characteristic metallic shimmer caused by tiny mica flakes (Fuchsite). Found commonly in India, Brazil, and Russia. Used by collectors to identify metamorphic quartz varieties.
