3.6" Green Augelite Crystals on Quartz - Peru

 
 
This is a beautiful crystal association that came out of the Mundo Nuevo Mine in Peru. It features green augelite crystals that formed from a bed of small clear quartz crystals. Some of the augelite crystals on this specimen exhibit a very faint green fluorescence under short wave UV, an attribute typically only found in specimens from Peru.

Comes with an acrylic display stand.

Augelite is an aluminum phosphate mineral that occurs as a product of metamorphism in phosphate bearing sedimentary rocks, in granitic pegmatites and in veins of high-heat hydrothermal ore deposits. Crystals can be colorless or exhibit green, yellow, white, blue, pink and red coloration depending on impurities present during formation. Due to the relatively low hardness of augelite, along with its brittle tenacity, seldom is it used for faceting into a gemstone.

The chemical formula of Augelite is Al2PO4(OH)3.

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
