This is one of the few very complete psuedomorphs we have seen from the deposit, over its run from 2008-2011. Most pseudomorphs are only partial, still very much cuprite and showing cuprite on some faces. This piece is complete all around and has great patina, on the intrictae copper crystals (which reach 2 cm). Interestingly, this is not a smooth copper pseudomorph, as with for example the material from New Mexico or Tsumeb in which copper replaces azurite or cuprite respectively. Here, the replacement seems to have happened in a more intricate process, resulting in small crystals of copper atop the actual pseudomorph, or comprising it. It looks more like a biological invasion than the typical replacement pseudomorph surface. Complete all around, and aesthetic
