3.1" Quartz Crystal Cluster with Epidote Inclusions - China

This is a beautiful, 3.1" wide quartz crystal cluster containing green epidote inclusions scattered throughout the crystals. Epidote aggregates can also be found perched atop some of the quartz crystals. It comes from the Hongxizhen unnamed mining area in the Sichuan Province of China. The base of this specimen has been cut flat for presentation purposes

Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
