Chalcoalumite (Type Locality) ex Mullane Coll.

Item Description

An OLD-TIME, much sought-after CLASSIC chalcoalumite specimen from the famous Type Locality - the Copper Queen Mine at Bisbee. Turquoise-blue chalcoalumite botryoids, in a really nifty enechelon pattern, cover the gossan matrix. Chalcoalumite is a RARE copper, aluminum sulfate. This is undoubtably old material, dating from the late 1800s-early 1900s, but no proof. This is a REALLY GOOD specimen of the rare species and famed locale. Ex Dennis Mullane Bisbee Collection. Value for such a rare old-timer?? It is TYPE LOCALITY, BISBEE, and a neat rarity...should be around $750
