4.7" Quartz Crystal Geode Section - Morocco

This is a 4.7" wide section of a quartz geode that was collected from Sidi Rahal, Morocco. There is some very slight purple coloration to the crystals (amethyst) and the red coloration can be attributed to iron oxidation. Comes with an acrylic display stand to assist with presentation.

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.
