9btcee ((CHALCOPYRITE)) $10 MINIMUM BID, Panasqueira, Covilha, Portugal, 8 x 4 x 3.5 cm, Cabinet | |
Here is a solid lustrous Chalcopyrite mostly covering with a dark coating that seems to cover the Chalcopyrite crystals from here. I think the dark coating may be just the crystal surface of the Chalcopyrite. |
