Malachite has completely replaced azurite on this classic specimen, which is unusually accented by primary malachite tufts on the replaced larger crystals. For my taste, this is the most aesthetic example in its size range I have ever seen of this important classic American find (they were found circa mid-1900's I have been told). This is a specimen with a rich and long history, that I have known for a long time and finally had a chance to get back at Tucson of 2011 with the sale of parts of the Roberts pseudomorph collection. It is a superbly composed specimen with the best aesthetics you could imagine in this size range, for these classic Bisbee pseudomorphs. The noted pseudomorph collection of dealer and collector, Ken Roberts, specialized in aesthetic and colorful pseudos. The piece was back-tracked to well-known Arizona collector Dick Graeme, who sold it to collector Jeff Kurtzman. It then passed into the Laura Thompson collection by the early 1990s (Laura kept her own suite of aesthetic, sculptural pieces she liked, apart from her husband Wayne's dealer stock and collection). I bought it from the Thompsons in 2001 and sold it to good friend and US-minerals collector (and now my gallery manager!), Kevin Brown within about 2 minutes, the time it took to walk from the Thompsons room back to my room and call him. Kevin kept this until 2009 when he sold it to Ken Roberts to fund another purchase. Ken, despite living in Tucson and specializing in pseudos, did not have one this good after 40 years of specializing in the material - that should tell you how much we all thought of this specimen. And now, 10 years after I first sold it to the day almost, I was able to buy it back at Tucson of 2011 as Ken sold his collection at the show. The piece has not been "over-cleaned" and retains some original pocket clay around the base. Joe Budd photos. NOTE ADDED from collector Les Presmyk, with thanks: The late 1940's, probably 1947 or 1948, from the 1300 level of the Campbell shaft
