Item Description

The Chalcopyrite specimens from Chimney rock are unusual for the species because they formed in botryoidal groups. This is confirmed Chalcopyrite, not Pyrite or Marcasite. This piece is a rarely seen UN-cleaned specimen of Chalcopyrite as it still has the black external oxidation. You don't see these on the market anymore, and it could be cleaned up to reveal the beautiful golden color underneath.
