It is a member of the Chalcedony Quartz family and is easily identified by its translucent yet sparkling appearance.
The appearance of Aventurine is so striking that its name is also used as a gemstone adjective when describing other gems with a similar sparkling optical effect: “Aventurescence”.
Aventurine gets its name from the Italian word “per avventura” - which means “by chance”. It is believed that in the 18th century, Venetian glass makers accidentally mixed in copper filings while producing their work and the result was a glass that sparkled.
Although green is the predominant colour for this gem, it can also be found in blue, yellow, reddish brown, greenish brown, orange and a most striking pale silvery colour.
Green Aventurine is associated with luck, chance and opportunity and is also believed to increase perception and develop creative insight.
Some highly superstitious people never buy a lottery ticket without their lucky Aventurine in their left pocket (the left pocket is chosen because both luck and left start with “L”).
Aventurine is also said to increase your libido and with Tourmaline is the anniversary gemstone for the 8th year of marriage.
Blue Aventurine is said to be a powerful healer that increases positivity and builds inner strength and self discipline. Several people have written that they have felt powerful and assured when wearing Blue Aventurine. If you’re a non-believer in myths and legends, Aventurine remains a truly beautiful coloured gem, whose lively sparkling mica flecks will have you spellbound,(“mica” is thought to come from the Latin word “mica” meaning “a crumb”, most likely derived from “micare”, which means “to glitter”).
Aventurine has been set in jewellery for many centuries and as it is typically found in larger sizes than many other gems, has also been used to create vases, bowls and even smoking pipes. Aventurine can be found in Brazil, India, China, Japan, the Ural Mountains in Russia, Tanzania, and the USA.
