With Antique Label

Description Tabs

Description
Locality: 
Altenberg, Erzgebirge, Saxony, Germany
Size Range: 
Miniature (4.5-7 cm)
Size: 
5.9 × 3.9 × 4.3 cm
Description

An interesting specoimen of massive boulangerite with minor chalcopyrite and sphalerite.  there are numerous circular formations of siderite? surrounding cores of boulangerite some of which show evidence of radiating acicular crystals.

The location as stated on the label is questionable with Bergmannstrost being near Bad Ems, whilst there are several Altenberg locations as well as Schonau locations, most of which do not have antimony mines. It is possible it could be Artenberg near Steinach, Baden-Wurttenberg. There are certainly opportunities for further research and I would welcome your thoughts.
