5.6" Natural Red Quartz Crystals - Morocco
This is a gorgeous specimen of iron-oxide coated quartz, collected in Morocco. This cluster is 5.6" long, and the crystals display rich red-orange coloring. The coloration is natural and due to iron oxidation both outside, and included within the crystals. An acrylic display stand will be provided with this specimen.
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.
