Aventurine Properties Facts and Photos
Aventurine Variety of 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 the inclusions a glistening or spangled effect can often be seen. This optical phenomenon is known as aventurescence. It's caused by sparkling internal reflections from microscopic inclusions of other minerals.
Although aventurine 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 crystals pink or orange and blue aventurine is caused in part by muscovite.
For aventurine to change colour the mineral inclusions must be present in great abundance. For this reason some argue it should be classed as a rock not a mineral.
The mineral aventurine is believed to have been named after the man-made material known as goldstone. Like aventurine it has a spangly or glitter-like appearance. The effect often referred to as aventurescence is caused as light reflects off tiny specs of copper embedded within the glass. 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.
Aventurine grades 6.5 to 7 on Mohs scale of mineral hardness.
In many articles online it's reported aventurine was discovered in 1837 by J.D Dan. Having looked into this we can find nothing factual to support it.
The person incorrectly referred to as J.D Dan is likely to be James Dwight Dana [1813 - 1895] American geologist, mineralogist, volcanologist and zoologist. Although he wrote about aventurine quartz and also aventurine feldspar, we can find nothing to indicate he discovered either. Bear in mind aventurine feldspar is sunstone.
Metaphysical Healing Properties
When used for its metaphysical properties aventurine protects the heart chakra and helps balance male and female energies. A stone of positivity it can reinforce decisiveness, strengthen leadership qualities and diffuse negative situations.
Aventurine promotes empathy and compassion, stimulates perception and enhances creativity. It can be used at home to protect against geopathic stress caused by exposure to electromagnetic fields (EMF). It calms anger and irritation replacing these feelings with patience and understanding.
Green aventurine is a comforting stone that protects and heals the heart. Blue is a powerful healer of the mind.
