This is a gorgeous quartz crystal cluster from Minas Gerais, Brazil. While two of the termination facets have been polished on the largest crystal, the rest of it has been left in its natural state. There is some additional facet polishing on the two smaller crystals along the side of the specimen.

This amazing display piece is accompanied by the pictured custom metal display stand.

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.
