This beautiful aggregate of curved Chalcopyrite crystals on Calcite is an old one, coming from Radhausberg, Kreuzkogel Massif, Gastein Valley, Hohe Tauern, Salzburg, Austria. This area is famous for its Medieval gold mine, but the mines were operated through to the mid-20th century. This specimen though is older, possibly mid-19th century judging by the accompanying handwritten label. The cluster (3 cm across) of Chalcopyrite crystals sits like a crown on top of this specimen and glistens with a beautiful golden to brassy metallic patina. The matrix is Calcite, but a line of grey sulphide passes through this - possibly Arsenopyrite. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
