Aventurine
Aventurine is a variety of quartz that contains tiny inclusions of shimmering minerals such as mica or haematite, creating a sparkling effect called aventurescence. The most common colour is green, but specimens also exist in blue, orange, brown and grey.
Major deposits include India, Brazil, Russia and Tanzania. Aventurine belongs to the quartz family with the chemical formula SiOâ‚‚. Its hardness is between 6.5 and 7 on the Mohs scale.
Well-known varieties are green aventurine (usually with fuchsite), blue aventurine (with dumortierite) and orange to red-brown varieties (with haematite or goethite).
