3.5" Glass-Clear Quartz Crystal Cluster - Brazil

This is a truly unique 3.5" wide cluster of high-quality quartz crystals from Minas Gerais, Brazil. The clarity of this quartz is spectacular. Some of the termination facets have been polished to reveal spectacular inner details in the crystals.

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.
