4.4" Carved, Strawberry Quartz Crystal Skull - Madagascar
This is a 4.4" long, polished strawberry quartz skull from Madagascar. This skull has been sculpted and polished from a larger chunk of strawberry quartz. Strawberry quartz earns it's color from iron oxide inclusions within the quartz.
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.
