Physical properties
Hardness: 7 Mohs; Color: Pale green with light marbling; Luster: Vitreous to waxy (when polished); Crystal system: Trigonal; Opaque to translucent.
Formation & geological history
Formed in magmatic and metamorphic environments where silica-rich fluids crystallize. Its green color and 'aventurescence' (shimmer) come from platy inclusions of green fuchsite mica.
Uses & applications
Commonly used for lapidary work, jewelry (beads, cabochons), home decor, and in metaphysical practices as a 'stone of opportunity'.
Geological facts
The name 'Aventurine' comes from the Italian word 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass.
Field identification & locations
Identify by its distinct green hue and internal shimmer. It is most commonly found in India, Brazil, and parts of Russia. This specimen has been tumbled and polished.
