Aventurine is a variety of translucent quartz with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as "aventurescence." When the inclusions are abundant and in a common orientation, their reflections can be eye-catching. This property, along with desirable colors, are what give aventurine its appeal as a gemstone. Aventurine is usually green, but also occurs in orange, yellow, red, pink, brown, white, gray, and blue.
The most common inclusion in Aventurine is Fuchsite, a green chromium-rich mica. It can be abundant enough in the quartz to give the material a green color. Some people think that Aventurine should be classified as a rock because the inclusions often make up ten to twenty percent of the material. Small reflective particles of other materials can cause aventurescence in quartz. Hematite and goethite can produce pink, orange, red, and brown aventurine. Muscovite and ilmenite can produce blue, gray, or white aventurine. Bright reflections and attractive colors make aventurine a popular semiprecious gemstone.
