Green Aventurine
A variety of Aventurine
What is Green Aventurine?
A type of Quartz and the most common Aventurine variety, green Aventurine is prized for its emerald-green color. This color is caused by the presence of fuchsite Mica inclusions in Quartz that reflect light. A less expensive substitute for Jade, green Aventurine is regularly formed into beads, pearls, and cabochons, and used with jewelry. It is also used for carved objects, vases, bowls, and sculptures.
