A sharp miniature, very aesthetic, from the fall-2011 finds here of this highly unusual pseudomorph (replacement): copper has completely replaced the earlier crystals of cuprite, preserving their form and making for a beautiful specimen at the same time. The crystals here reach 1.1 cm in size and show a superb degree of symmetry and perfection in form. This piece has a surface sparkle to it, caused by a later generation of microscopic copper deposition, that is hard to capture in photos without seeming to "over-light" the shots. So, in person, it is correct in this color but is very sparkly and lively, compared to most copper specimens. I have never seen such fine copper replacements after cuprite, from other locales. This new (and self-liquidating) mine has produced some amazing things during its short, recent run. Joe Budd photos.
