Peach Aventurine Crystals

Aventurine or aventurine quartz as it's also known is made up primarily of the mineral quartz.  Minute inclusions of mica, fuchsite or hematite are often present.  These can give the stone a sparkly appearance that's known as aventurescence.

This optical phenomenon is caused as light reflects off the mineral inclusions.  Where present in abundance they cause the stone to change colour.

The most common colour of aventurine is green but it also occurs in orange, yellow, red, pink, brown, white, grey and blue.

Green is caused by a chromium-rich mica called fuchsite.  Lepidolite mica can turn the stone pink, red or purple.  Iron oxides such as hematite and goethite produce pink, red, brown and shades of orange. 

Although often described as a mineral aventurine is a rock.  Quartzite is a metamorphic rock that began life as sandstone.

Many stones sold today as aventurine exhibit little or no aventurescence.  Finding polished stones that exhibit this characteristic can be difficult.

Peach aventurine is a trade name for a deep reddish-orange coloured stone.

Aventurine is believed to have been named after the man-made material known as goldstone.

The colour of peach aventurine is caused by the presence of iron oxides.
