Aventurine is a variety of chalcedony quartz characterized by its translucency and sparkly metallic inclusions. Glittery inclusions are typically composed of muscovite mica, which usually results in medium to dark green aventurine stones with a silvery green or blue sheen. Aventurine is a translucent to opaque variety of microcrystalline quartz. It contains small inclusions of shiny minerals which give the stone a sparkling effect known as aventurescence. Inclusions of mica will give a silverish sheen, while inclusions of hematite give a reddish or grayish sparkle. Aventurine is known to be a stone of luck.
