Green Aventurine Crystals - Included Quartz
Green aventurine can look very similar to green quartz, but it's a different stone.
Aventurine is a type of quartz with minute, plate-shaped inclusions. Avenurine often has a shimmering effect as light reflects off the metallic inclusions.
Many different optical effects exist in rocks and minerals, many with their own names. The term for how light reflects of these metallic inclusions is known as aventurescence.
Although fuchsite (fook~site) tends to be the most common inclusion, it can also be lepidolite, hematite, goethite (ger~tite), muscovite or ilmenite.
When present in abundance, they can influence the stone's colour. The green in aventurine comes from fuchsite, a chromium-rich mica.
These finely polished green aventurine crystals are medium-sized tumbled stones, but size does vary from piece to piece. This is common for stones produced in a rotary rock tumbler.
