Cuprite with Native Copper & Native Silver replacing Cuprite Rubtsovskoe Cu-Zn-Pb deposit, Rudnyi Altai, Altaiskii Krai, Western-Siberian Region, Russia 1.8cm x 1.7cm x 1.55cm

Description/Interesting Notes: A fantastic example of cuprite with native copper and silver from Russia!!! While there were a number of cuprite and native copper after cuprite specimens to be found at the Tucson Show, this was one of just a few such examples we found where the native copper was also being replaced by native silver as well!!! This specimen consists of a complex group of intergrown cuprite crystals that is being replaced by native copper AND native silver!!! The cuprite is lustrous, sharp, and complete!!! The native copper is well crystallized, but it is also intimately associated with crystalline native silver!!! The resulting patina and hue is quite handsome and unique!!! The native silver replacing the native copper is well crystallized and distinct, although there are areas where it appears they could be mixed as well!!! There is also a mass of finely dendritic native silver present as well, this is the more common presentation, where the native silver is likely a pseudomorph after miersite or related halide!!! This specimen is as handsome as it is unique!!! The crystal is in fantastic condition and displays magnificently all around!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!!
