Aventurine is a type of quartz characterised by minute 'platy' inclusions. This describes tiny inclusions of other minerals that are often shaped like a plate.
The most common colour of aventurine which is green comes from inclusions of fuchsite, mica or hematite.
It can also be found in pink, blue, yellow, orange and several other colours.
Blue and green aventurine comes mostly from India. Other colours can be found in Spain, Chile and Russia.
The sparkly appearance that can often be seen in aventurine is known as aventurescence. It's caused by the reflection of light off minute inclusions.
Aventurine is believed to have been named after the man-made material known as goldstone.
