7.4" Clear, Double-Terminated Quartz Crystal Cluster - Brazil
This is an incredible cluster of high-quality, double-terminated quartz crystals from Minas Gerais, Brazil. The clarity of this quartz is spectacular and the terminations are in great condition with only some minor chipping to a few of the crystals. All of the facets and faces are natural and haven't undergone any polishing.
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.
