4.2" Polished Quartz Sphere - Madagascar

This is a 4.2" wide, polished quartz sphere from Madagascar. This sphere has been polished into a perfect round sphere from a larger chunk of quartz. The chatoyant portions of the sphere are stunning, and the specimen weighs 3.9 lbs. Comes with pictured display stand.

This sphere has a yellow-brown tint to it, however i'm hesitant to label it as citrine due to the scarcity of natural citrine.

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.
