Hetaerolite is a rare zinc, manganese oxide. So, we have here a showy, rare and old combination specimen from the famous Copper Queen Mine at Bisbee. Dark, rust-brown, bubbly hetaerolite totally coats a copper leaf. The botryoids look like a grape cluster, which is nicely accented by a diagonal flat plate of goethite on one side. Ex. Dave Stoudt Collection, who according to their catalogue, purchased this piece in Bisbee in 1994 from then Bisbee rock shop owner Chuck Youngblood.
