Ochre-brown to beige dolomite crystals sit on the original matrix and form a compact, clearly structured crystal group. The earthy colors and characteristic crystal development give the specimen the distinctive appearance of a historic find from the Siegerland mining district.
The crystals show the rhombohedral form typical of dolomite and stand out clearly from the darker matrix. This makes the piece a useful reference specimen for the mineralization of the former Eupel Mine.
