Aventurine Facts Properties and Great Photos
Aventurine Variety of the Mineral Quartz
Aventurine is a translucent variety of the mineral quartz which can usually be identified by the presence of platy inclusions. Platy describes individual crystals that are small and flat like a plate. They often have a flaky appearance. Mineral inclusions referred to as platy are mostly mica or hematite.
As light reflects off platy inclusions in aventurine, a glistening or spangled effect can often be seen. This optical phenomenon known as aventurescence is caused by sparkling internal reflections from microscopic inclusions of other minerals.
Although aventurine quartz occurs in different colours, green, blue and orange are the most common. Green aventurine is caused by inclusions of fuchsite (fook~site). Brown is caused by the presence of pyrite. Hematite and/or goethite (ger~tite) turn aventurine pink or orange and blue aventurine is caused in part by muscovite which is a type of mica.
In order for aventurine to change colour the mineral inclusions must be present in great abundance. For this reason some argue the stone should actually be referred to as a rock not a mineral.
Aventurine is believed to have been named after the man-made stone known as goldstone. This material originated in Venice hundreds of years ago. Goldstone just like aventurine has a spangly or glitter-like appearance. The effect is caused as light reflects off tiny specs of copper embedded within the glass. For this reason goldstone is also known as aventurine glass.
Most of the world's supply of blue and green aventurine comes from India. Off-white and grey to yellow-orange coloured stones can be found in Chile, Spain and Russia. Other colours can be found in Brazil, Austria and Tanzania. Taganai Stone river in the Southern Urals of Russia is reported to be the world's largest deposit of aventurine.

Aventurine is a quartzite which is a type of metamorphic rock that started off as sandstone. During the Stone Age primitive tools were made of quartzite when flint was not available. Although not quite as easy to work with, it's hard yet brittle which makes it relatively easy to shape.
The mineral aventurine grades 6.5 to 7 on Mohs scale of mineral hardness.
