This specimen once was a rosette of intergrown, bladed, azurite crystals which have been totally pseudomorphed by copper. The specimen exhibits a very nice old patina. These complete floaters are quite rare today, and were found in the 1940s through 1950s I am told. They show a remarkable complete replacement of azurite by copper, and are to my knowledge unique in their aspect, form, and size compared to other azurite pseudomorphs
