9.3" Tall, Quartz Crystal Cluster - Brazil
This is a beautiful cluster of quartz crystals from Brazil. The massive center crystal is 8.5" long (from lowest measurable point) by 3.7" wide at its thickest point. The largest crystal's termination has been polished. The entire cluster weighs 10.6 lbs and stands aesthetically on its own.
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.
