Chalcoalumite is a rare copper, aluminum sulfate and the historic Copper Queen Mine is the type locality. This sculptural specimen has vugs on the front and back lined with pretty, powder-blue, bubbly, botryoidal chalcoalumite. Extremely rich and undoubtedly old material, dating from the late 1800s-early 1900s, but no proof. Ex. Dennis Mullane Bisbee Collection.
