Schöne Aussicht mine is one of the most famous localities for the rare lead iron phosphate sulphate hydroxide species Corkite. This very large thumbnail specimen comes from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021) and features several distinct shapes of Corkite crystals, from a finely crystallized glossy crust on massive Goethite, to larger (0.4 to 0.9 mm wide) pseudocubic and wedge-shaped crystals in small cavities on the back of the specimen. Under strong illumination, or under microscopy, the translucent Corkite crystals present the classic yellow-olive green colour. A very good crystallized specimen of this rare secondary species.
