About Aventurine
Formula:
SiO2
Name:
From Italian "a ventura", meaning by chance (Aventurine glass, i.e. glass with small colouring copper inclusions, was first prepared accidentally in the early 18th century in Italy).
A variety of quartz containing glistening fragments (usually mica, such as fuchsite, but also hematite), which can be cut and polished as a gemstone. Most commonly, when the public encounters this stone, it is in the form of green stone beads that can range from a pale to a medium green colour. Frequently, these beads have been treated with oil to make the stone look a darker colour than it would naturally, or even dyed to make the colour more attractive. Aventurine can also be found in other colours, but the most common colour is green. Aventurine is a general term that is used by different commercial interests to mean several kinds of stones (compare Aventurine Feldspar).
Compare with prasiolite, prase and plasma. Not to be confused with Aventurine glass or goldstone, a synthetic reddish (due to copper inclusions) or greenish (due to chromium) glass used as a "gem" material.
