Physical properties
Hardness: 7 (Mohs scale), Color: Reddish-orange to brown, Luster: Vitreous to waxy, Crystal Structure: Trigonal, Cleavage: None, Specific Gravity: 2.64-2.69
Formation & geological history
Formed or recrystallized in metamorphic environments where quartz-rich deposits are subjected to heat and pressure, allowing the inclusion of iron-oxide minerals like hematite which provide the red color.
Uses & applications
Commonly used for tumbled stones, decorative carvings, jewelry beads, and as a healing crystal in metaphysical practices.
Geological facts
The name 'Aventurine' comes from the Italian 'a ventura,' meaning 'by chance,' originally referring to the accidental discovery of aventurine glass. The characteristic glittery effect is known as adventurescence.
Field identification & locations
Identified by its sparkly iron inclusions and quartz-like hardness. Often found in India, Brazil, and Russia. Collectors look for even color distribution and strong 'flash' or shimmer.
