9.1" Polished Quartz Geode "Egg" - Madagascar

 
 
 
 
This is a beautiful 9.1" tall polished egg, made from a quartz geode. This mineral egg was mined, shaped and hand polished in Madagascar. The yellow coloration of the quartz can likely be attributed to iron oxidation.

Comes with the pictured display stand.

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.
