This is a beautiful druzy gray quartz crystal geode section from the mines near Artigas, Uruguay, that's polished into the shape of a heart. The custom metal stand makes for a very aesthetic display piece.
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.
