4" Tall, Quartz Encrusted Stalactite Cluster - India
This is a fantastic specimen that contains stalactites that are encrusted in layers of small quartz crystals. The specimen was collected from Maharashtra, India and is 3.1" wide by 4" tall. The blue-green mineral that the quartz is coating, is unidentified.
There is a repaired crack at the base of the largest stalactite where it likely broke off during the extraction process.

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.
