Pietersite - Polished Slice

Size: 95 mm x 40 mm, 30 grams

This exquisite and rare stone is only known from one farm in Namibia.
 
Pietersite is a variety of Chalcedony (Quartz), with embedded fibers of amphibole minerals with varying degrees of alteration. Its colour could range from blue-grey, brown, golden-yellow, black and seldomely with red patches. The fibers cause a chatoyancy, similar to that seen in the well-known Tiger's eye.
 
This is a beautifully polished slice with a lot of blue colour. It is polished on the front face and left rough at the back. A really beautiful piece.
