Thanks, Roger. The label´s origin is the so-called Naturaliensammlung der Lehrerbildungsanstalt Amberg/Bavaria.

Hi Andreas,
as usual, very interesting specimens from famous German localities. Only one correction concerning the large quartz from Medenbach: The Herborn area and the Medenbach quarry are not in Rhineland-Palatinate, but in Hesse (only about 45 km away from me). There are also several places with that name in Rhineland-Palatinate, but the one with the limestone quarry is in Hesse (though only a few km away from the border between Hesse and Rhineland-Palatinate).
Cheers!
Tobi

Hi Andreas. The german chabazite is gorgeus!! I also like the galenas. Well, I am not a connoisseur of german minerals, of course, but if you go on posting such pictures maybe I will improve my little knowledge.
