Aventurine is found in India, Chile, Spain, Russia, Brazil, Austria, and Tanzania. It is a 6.5 on the Mohs scale of hardness. This mineral is often mistaken for amazonite or jade.
It is interesting that the name for the stone is derived from an accident. Sometime during the 18th century, Venetian glass workers were preparing molten glass when copper filings accidentally fell into the batch producing a glass with sparkles. The name aventurine comes from the Italian “a ventura,” which means”by chance”.
Deposits are found in Brazil, India, Austria, Russia, and Tanzania.
