Pyrite
Parey gravel pit, Spektefeld, Spandau, Berlin, Germany.
11 x 7 cm
Normally, you wouldn´t expect nice minerals coming from Berlin, would you? However, years ago a lot of gravel pits were a good opportunity for the West-Berlin collectors. Two famous examples are the gravel pits Parey and Vering&Waechter in Berlin-Spandau, especially for fossil collectors. Excellent amber specimens are known and - pyrite crystals in clay. The shown one is stable since more than 50 years, consisting of undamaged cuboctahedrons up to 2,5 cm and the best I ever saw of these sorts. It was found in 1961, the year the Berlin Wall came into being... |
