Aventurine is a form of quartz which is a hard, crystalline mineral composed of silicon and oxygen atoms and is the second most abundant mineral in Earth's continental crust, behind Feldspar. Aventurine is characterized by its translucency and the presence of platy mineral inclusions that give a shimmering, reflective or glistening effect termed aventurescence. The most common color of Aventurine is green, but it may also be orange, brown, yellow, blue, or grey. Aventurine’s most common inclusion is Fuchsite, a green chromium-rich mica. Flakes of Lepidolite Mica can impart a pink, red or purple color. Hematite can produce pink, orange, red, and brown Aventurine.  Muscovite can produce gray, yellowish or silvery Aventurine. Dumortierite inclusions cause the Aventurine to be blue.

Small amounts of Aventurine have been found in many parts of the world. India is by far the most important commercial producer of Aventurine. Brazil is the second-place producer. South Africa, Russia, Spain, Austria, and Tanzania produce Aventurine.
