Copper psm. Azurite
Copper Rose Mine, USA
Copper Rose Mine , San Lorenzo, Georgetown District, Grant Co., New Mexico, USA
A superb psuedomorph of copper after an azurite rosette from the Copper Rose Mine Grant Co., New Mexico, USA! These superb pseudomorphs are among the most rare and coveted US psuedomorphs out there – most were collected many decades ago, going back to the days of George English, famed mineral dealer at the turn of the 20th century! This specimen developed as a floater, having been a fully crystallized rosette of azurite. Its’ chemistry then altered to copper, which was later partially oxidized, giving it a wonderful green color. This one is rather large for the material, and the crystals are sharp. So often, these can been drab – the pseudomorphs nearly amorphous and the color a dull brown. Not the case with this specimen, which is nearly undamaged, minus a crystal on the bottom of the backside.
