Copper with Azurite, Malachite and Cuprite (ex Rich Kosnar Collection)

Item Description

A beautiful association specimen of the famous and very hard to find Coppers from the Cashin Mine in southwestern Colorado. The pieces are not only hard to find in today's market, but they are seldom seen with such beautiful secondary associated minerals like this. The piece has a fine antique patina which is highlighted by gorgeous intense blue colored patches of Azurite along with minor mint green Malachite and a thin coating of reddish-brown micro Cuprite. A great piece for a native element collector, a secondary mineral collection, or a Colorado mineral suite. The Cashin Mine was finished 50 years ago (early 1970s), so don't miss out on this one as very few are available on the market today. This locality dates back to the late 1890s, and produced nearly two million pounds of Copper during its lifetime, though specimens are fairly obscure on the market. From the personal collection of Richard A. Kosnar (1946-2007) the well-known mineral dealer and collector from Colorado. Rich was the namesake for the rare phosphate species, Kosnarite. Rich's collection number on this specimen is #C1062.
