PMM-NM8Pyrite FeS₂

Jochenberg Quarry, Bad Kösen, Naumburg, Burgenlandkreis, Saxony-Anhalt, Germany

Sceptre of a Pyrite octahedron on the top of a lath-like Pyrite (or Marcasite?) crystal.
Field of view is approx. 0.5 cm.
Found in 1985 at the 1st level of the Jochenberg Quarry, Bad Kösen, near Naumburg, Saxony-Anhalt, Germany.
Notice: There exist specimens with a couple of such sceptres with varying isometric forms of the Pyrite "knobs" on the top. Most commonly are cubooctahedric forms, but I have also found a singular icosahedron.
These specimens are now in the Mineralogical Collection of the Friedrich-Schiller-University Jena, Thuringia, Germany (curator: Dr. Birgit Kreher-Hartmann).
