Blue-green Fluorite crystals reaching 3.3 CM with several distinct Siderite crystals on and between the Fluorites. A nice old German piece with labels from A. Kranz and another earlier collection, this is in very good condition overall. This locality was worked for a very long time and finally closed about thirty years ago, though we believe this specimen is at least 100 years old. The Siderites are in well-formed lath type crystals and show curved faces much like Dolomites. A classic piece from the southern Harz Mountains, we rarely see specimens from this locale here in the USA, this one is well better than average.
