Y1617 Copper ps. Cuprite
A cluster of copper psudomorphs after cuprite octahedrons. Along with the massive amounts of cuprite that came from the area, there was a relatively small find of these very interesting pseudomorphs made in 2011.
Unlike the cuprites which flooded the market, the prices on these things have been consistently high-- these pseudomorphs were only found towards the end of work in the cuprite bearing zone and in relatively small quantities.
