Mineralogy: Aventurine is a variety of
quartz. The name was originally a trade name, but is now widely accepted as the
mineralogical name. It forms massively (with no distinct crystal faces), and is
characterised by its spangled or glittery appearance, which is due to the
inclusion of other minerals. It is most commonly dark opaque green, the
colouration and sparkle due to included fuchsite (green mica), and it often has
pyrite inclusion as well. Brown aventurine is coloured by pyrite, and red
aventurine by hematite. It also occurs in yellow, orange and blue. It is
generally sold as a tumbled or polished stone, or in jewellery. In the past,
the name aventurine was also applied to certain varieties of feldspar, sunstone
in particular.
