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.
History and Tradition: The name comes from the Italian ventura, meaning “chance” – as in it was found by chance. There are no traditions associated with aventurine
