A cluster of very sharp and distinct cuprite crystals (to 1.6 cm) that have pseudomorphed to copper.
Despite that fact that it is not the largest of the pseudos I have posted on this page, it is probably my favorite of the group.
There seems to have been a small area were silver was naturally plated onto the specimen-- this is visible in the image directly below the description, on the left-hand side of the specimen.
This area has been producing cuprite for about 3 years now, but in 2011 there were also finds of these very interesting pseudomorphs. The prices on these things have been consistently high-- unlike the cuprites which came out in massive quantities (and whose prices have moderated somewhat as a result), these pseudomorphs were only found towards the end of work in the cuprite-bearing zone (which is now finished), and in relatively small quantities. In other words, these wont get any cheaper, only more expensive.
