2.5" Orange Quartz Crystal Cluster - Diamond Hill, SC

The Diamond Hill Mine is located in the southern portion of the Appalachian Mountains in South Carolina. Erosion over millions of years exposed this 3-acre spot of mountain that produces some of the widest varieties of quartz variations in the world. Quartz variations such as amethyst, smoky, skeletal(elestial), milky, phantomed, iron and manganese oxide coated, and even aura quartz are know to have been deposited here through silica-rich hydrothermal processes. Other minerals including beryl, epidote, and garnet are known to come out of this location as well.

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.
