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

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 general public encounter this stone it is in the form of green stone beads that can be anywhere 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 other colours but the most common colour is green. Aventurine is a general term that is used by different commercial interests to mean several different kinds of stones (compare Aventurine Feldspar).

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.
