Pristine, 4.6" Prase Quartz Crystal Cluster - Mongolia

 
 
This is a pristine cluster of green prase quartz crystals that were collected from the Huanggang Mine in Mongolia. The green color of the quartz can most likely be attributed to hedenbergite inclusions within the quartz. These needle-like inclusions become apparent when backlighting the crystal and looking at the crystal's termination.

Silicon Dioxide, also know 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.
