Copper pseudomorph after Azurite (''rose'') (classic material)

Item Description

Pseudomorphs are one of the more interesting phenomenons in the mineral world, as one species replaces another, but retains the form of the original mineral. They are found in all kind of environments around the world, but the pieces from the Copper Rose Mine are distinctive and unique. I'm genuinely a big fan of these gorgeous specimens, not only for their fantastic form, but also the fact that this might be the only locality where a native element replaces a secondary carbonate species that is derived originally from the same element (Copper gives way to forming Azurite and then is pseudomorphed back to Copper). The first thing that I notice when I look at this specimen is the superb sharpness of the crystals. All of the bladed crystals on this piece (that once were Azurite) are very discernible, and not tightly "jumbled" together. Additionally, the piece has a fine antique looking patina, giving it a lot of character. The piece is a complete "floater" with no damage or point of attachment. Many of these gorgeous pseudomorphs date back well over a century when they were collected by George English and A.E. Foote in the 1890's and were sold to Eastern collectors and museums along with European collectors. These pieces are to my knowledge unique in their aspect, form, and size compared to other any other Azurite pseudomorphs. This is certainly a good sized piece for the locality, and fine quality in terms of form and sharpness. One rarely sees the marvelous specimens on the market these days, and if you're a fan of secondary ore minerals, native metals or attractive pseudomorphs, do NOT pass up the chance to get a really good example of this famous material for your collection.
