Aventurine

Aventurine is a translucent quartz with a bright green color, often containing mica or hematite inclusions that create a sparkling effect known as 'aventurescence'. It forms in metamorphic rocks and is primarily found in Brazil, India, and Russia. Historically, it was used by ancient peoples as an amulet for luck and protection, while in China it was called the 'stone of the emperor' for its association with prosperity.
