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... (Author: Andreas Gerstenberg)

Some Austrian localities (as Nassereith, Imst or Bleiberg) are known for wulfenites. However, the wulfies are found on the Bavarian side of the border too. A once famous locality was the Höllental molybdene mine near Garmisch-Partenkirchen. During Second World War the mine was taken up again for a short time. I never saw a real good Höllental sample (not on pictures, not in person...) but it is told that these wulfenites were as good as the Austrian ones from Bleiberg, Carinthia. The only sample I ever saw (thanks to ebay) is now in my collection. I think this specimen is just a reference (crystals up to 5 mm), but it gives a suspicion of the Höllental wulfenite´s quality... but you wouldn´t pick up something like this if it´s labelled with Mexiko or Arizona.

The copper shist district Mansfeld-Eisleben-Sangerhausen (Saxony-Anhalt) is - among other things - famous for its gypsum specimens. Most collectors know the colorless and grey crystals from Eisleben. From Sangerhausen (Thomas Müntzer shaft) brown elongated crystals are frequent. A certain variety are "Weißkopfgipse" (white-headed gypsum) from that locality - black crystals with colorless tops. There are big samples with crystals standing closely packed: a feast for the eyes! (Author: Andreas Gerstenberg)
