6.6" Orange Quartz "Stalactite" Formation on Wood Base - Uruguay

This is a beautiful, sparkling "stalactite" cluster, of orange, druzy quartz mined Artigas, Uruguay. It comes from the same mines as the dark Amethyst that this area is renowned for, but these orange crystal pockets are a much rarer find. The sides of the specimen have been polished, leaving a beautiful agate "rind" and it comes with a custom-made wooden display base.

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.
