5atdbr ((CHALCOPYRITE pseudomorphed?, COVELLITE?)), $2 MINIMUM BID, Alice Mine, Clear Creek County, Colorado, 2 x 1.8 x 1 cm, Thumbnail | |
Here is a thumbnail sized loose Chalcopyrite crystal. The crystal has a dark coating with a few metallic blue specks that are probably Covellite which does occur at this mine. This crystal is in two halves. The Chalcopyrite looks like a pseudomorph since the inside is not golden Chalcopyrite. |
