6.4" Tall Sparking Quartz Geode Section on Metal Stand - Uruguay
This is a beautiful, sparkling plate of purple/orange quartz mined Artigas, Uruguay. It comes from the same mines as the dark purple amethyst that this area is renowned for, but these crystal pockets are a much rarer find. The orange/purple coloration is a result of orange inclusions/impurities within the quartz and some slight purple coloration to the quartz/amethyst. The edges of the specimen have been polished, leaving a beautiful layered agate "rind" and it comes with a custom-made metal display stand.
About Quartz
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.
