Bright Robin's egg blue Chalcoalumite covering matrix. These specimens are very hard to come by now as the locality is now part of a national park. This old copper mine began operation in 1892, stopped operation around 1907, and became a part of the national park in 1940. The specimen is likely over 100 years old! From an old collection and comes mounted in a plastic box.
