The remarkable Rubtsovskoe Cu-Zn-Pb Deposit at Rudnyi Altai, Western-Siberian Region, Russia operated for just ten years from 2005 until 2015, but during that time it established itself as the source of some of the finest crystallized Cuprite specimen ever known. Not only that, but some of these were associated with Native Copper pseudomorphs after octahedral Cuprite crystals which, if not unique to the world of mineralogy, must be exceptionally rare. The pseudomorphs were discovered in 2011 and quickly snapped up as fascinating mineralogical oddities, but most specimens were in the miniature size range. This larger cabinet-sized display specimen is phenomenal and must rank as one of the finest in existence. Not only does it display extremely sharp, well-defined orange, metallic, Native Copper replacements after perfect octahedral Cuprite crystals to 1.6 cm on edge, but on either side of the specimen are clusters of original, unaltered deep purple-red octahedral Cuprite crystals to 1.8 cm on edge, or over 2 cm across in their longest direction. Neither the Cuprite, or Native Copper pseudomorphs after Cuprite appear to show any damage, making this a world-class, museum quality display specimen from this unique occurrence.
