The name comes from the Italian “A Ventura” meaning “by chance”, when copper was accidentally dropped into molten glass in the 18th century. Now that man-made glass is called Goldstone, and the name Aventurine was given to the quartz, which is found all over the world. Aventurine is a silicon dioxide with hexagonal structure, characterized by platey mineral inclusions of mica. The mica inclusions give it a shimmering, metallic glitter optical reflectance that is known as aventurescence. Most aventurine is green to blue, due to chrome bearing fuschite inclusions, but also comes in orange/pink/red/brown/yellow/gray due to hematite, lepidolite, lepidocrocite, goethite, biotite or other mica mineral inclusions. Be wary of extremely bright colored specimens as they may have been dyed. Aventurine is translucent to nearly opaque, sometimes striated and always with aventurescence.
