1.8" Lustrous Red Hubnerite and Quartz Crystal Association - Peru
This is an eye catching red hubnerite (manganese tungstate) and quartz crystal association. It comes from the Huayllapon Mine (Huallapon Mine) in the Pallasca Province of Peru. The entire specimen measures 1.8" wide.
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.
