Native Silver with Cerussite & Brochantite on Chalcocite Calumet & Arizona Mine, Lowell, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona 6.26cm x 4.7cm x 3.12cm

Description/Interesting Notes: A rare, old time example of native silver from Bisbee!!! This specimen consists of a dark, massive chalcocite matrix that hosts numerous bright, leaf-like crystals of native silver in association with dramatically compressed cerussite crystals and bright green crystals of brochantite!!! The native silver is actually crystalline material, not simply massive leaf silver!!! The contrast of the silver against the dark chalcocite makes for a rather handsome display!!! However, upon further inspection there is much more going on here than it might first appear!!! When I examined this specimen with the stereoscope I was amazed to find that these silver crystals are actually pseudomorphs after the cerussite!!! The crystallization that the silver exhibits is identical to the cerussite crystals and there are a few instances on the specimen where they are actually intergrown!!! This specimen is simply amazing in person!!! This specimen was recently trimmed from what was a much larger specimen and the newly exposed silver has a very lively tin-white metallic brilliance whereas the older, previously exposed areas of silver have an somewhat "antique" patina to them!!! The resulting combination of patinas is quite striking!!! Of the group of specimens trimmed from the original piece of silver-rich chalcocite - there were only a few, this specimen was the best - and it is also the last!!! If so desired, more silver could still be exposed on this specimen or it could be easily split into more rich specimens!!! There are rich veins of silver running through this specimen in several areas and there is visible silver on nearly every side of the specimen!!! This specimen is simply amazing in person!!! The pics hardly do it justice!!! Rare, old time material!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!!
