Aventurine Variety of Quartz

Aventurine is a translucent variety of the mineral quartz.  It can usually be identified by the presence of minute inclusions. These are often described as 'platy' in reference to their plate-like shape.  They often have a flaky appearance.

Mineral inclusions described 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 correctly 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 shades of yellow/orange are the most common.

Green aventurine is caused by inclusions of fuchsite (fook~site).  Pink, orange, red and brown varieties tend to come from pyrite, hematite or goethite (ger~tite).  The colour of blue aventurine comes mostly from muscovite.

Aventurine is believed to have been named after a man-made material known as goldstone.  Like aventurine it has a spangly or glitter-like appearance.  The effect also referred to as aventurescence is caused as light reflects off copper that has crystallised within the glass.  Goldstone is also known as aventurine glass.

Although impurities in a mineral will often cause a change in colour, when present in abundance inclusions can also change the colour of a stone.  One example is aventurine and another is goldstone.  The colour of the brownish-orange variety comes purely from the inclusions of copper.

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.

Although often referred to as a mineral aventurine is in fact a rock.  It's a quartzite which is a type of metamorphic rock that started off as sandstone.  Rocks and minerals are different materials.

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 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 (sunstone), we can find nothing to indicate he discovered either.

Aventurine Healing Properties

When used for its healing properties aventurine protects the heart chakra and helps balance male and female energies. A stone of positivity, it helps heal heartache and brings emotions back into alignment.  

Aventurine is a stone for decisiveness that strengthens leadership qualities and diffuses angry situations.  It promotes empathy and compassion, stimulates perception and enhances creativity. When faced with anger and irritation it replaces these feelings with patience and understanding.

Green aventurine is a stone of communication that will help you express yourself in an assertive but eloquent manner.  Although a great crystal for career success, it also raises awareness about the importance of a healthy work-life balance.

Aventurine will encourage you to distance yourself from the manic pace of everyday life.  It calms erratic thoughts and may help compulsive behaviour.  

One of the great benefits of green aventurine is its ability to bring energy into balance. When energies are flowing freely it enables us to deal with difficult matters in a calm and more logical manner.

Aventurine can be used by healers or those who help others.  It offers protection from unwanted energies, prevents lethargy and maintains a positive state of mind.
