Physical properties

Hardness: 7 Mohs; Color: Pale to forest green; Luster: Vitreous; Crystal Structure: Trigonal (hexagonal); Specific Gravity: 2.63-2.65; Cleavage: None (conchoidal fracture).

Formation & geological history

Forms in metamorphic rocks like phyllites or schists and in hydrothermal veins. The green color is caused by tiny inclusions of green fuchsite mica.

Uses & applications

Commonly used for lapidary work, jewelry (beads, cabochons), carvings, and as a popular stone for collectors and metaphysical use.

Geological facts

The name 'Aventurine' comes from the Italian 'a ventura', meaning 'by chance', originally referring to the accidental discovery of aventurine glass. The natural stone's shimmer is known as aventurescence.

Field identification & locations

Identify by its characteristic green color and shimmering mica inclusions. It is widely found in India, Brazil, and Russia. It mimics jade but is harder and has a 'glittery' internal reflection.
