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 is a term used to describe individual crystals that are small and flat like a plate and often have a flaky appearance.  Mineral inclusions referred to as platy usually tend to be mica or hematite (the mineral form of iron oxide).

As light reflects off the platy inclusions in the mineral 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 several different colours, green, blue and orange are the most common.  The colour of green aventurine is caused by inclusions of fuchsite (pronounced fook~site), brown is caused by the presence of pyrite, hematite and/or goethite (pronounced ger~tite) turn the stone pink or orange and blue aventurine quartz is caused in part by the mineral muscovite which is a type of mica.

In order for aventurine to change colour the mineral inclusions must be present in great abundance and for this reason, some argue the stone should actually be referred to as a rock instead of a mineral.

Aventurine is believed to have been named after aventurine glass otherwise known as goldstone which is a man-made material that originated in Venice hundreds of years ago.  Goldstone just like aventurine has a spangly or glitter-like appearance that's caused as light reflects off tiny specs of copper that have purposefully been embedded within the glass.  For this reason it's often called aventurine glass. 

Most of the world's supply of blue and green aventurine quartz comes from India.  The off-white, grey and yellow to orange coloured stones come from Chile, Spain and Russia and other varieties 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 made it relatively easy to shape. 

The mineral aventurine grades 6½ to 7 on Mohs scale of mineral hardness.
