For sale is a specimen of pale turquoise blue micro crystals of McGuinnessite from Gulsen quarry, Austria. The accompanying minerals I would say are gypsum and calcite, thou I can not find any other pics of these minerals directly in association with McGuinnessite. McGuinnessite is a very rare anhydrous copper carbonate found in collector specimens for a hand full of locations worldwide. This minerals was first identified in 1981. This comes from the collection of the late Russel Knowsky (Qld MinSoc)
