A fine, old-time, classic chalcoalumite combination specimen from the Type Locality - the Copper Queen Mine at Bisbee. Vugs in the striking, stacked limonite box-work are totally lined with powder-blue chalcoalumite botryoids. Tufts and sprays of malachite are richly and aesthetically scattered about. There are even a few azurite crystals. Chalcoalumite is a rare copper, aluminum sulfate. This is undoubtedly old material, dating from the late 1800s-early 1900s. Ex. Dave and Emily Stoudt Collection and according to their catalogue and label, was purchased from then Bisbee rock shop owner Chuck Youngblood in 1988.
