Clearance Lot: Spruce Ridge Quartz Crystals - 140+ Crystals
This is a clearance lot of quartz crystals from Spruce Ridge claim in King County, Washington. They were collected during a dig with Bob Jackson in the late 90's. They range from .5" to 2.5" long, with most in the 1" to 2" range. Most of the crystals have been cleaned, though some are still coated in iron oxidation. Some of the specimens are clusters.

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.
