An azurite specimen from this classic German locality, to be enjoyed under magnification. These are aggregates of azurite crystals, some isolated, richly faceted, with transparence, brilliance and the characteristic colour. With globular aggregates of malachite. Very aesthetic.

RM3042   Silver and Chrysocolla

Clara Mine, Oberwolfach, Ortenaukreis, Freiburg, Baden-Württemberg, Germany

The silver specimens from this classic German mine has been known for a long time, but in these specimens silver is included in chrysocolla, of an intense greenish blue colour, and shows a remarkable luster, sometimes with golden iridescence. Under magnification we can see facets of crystals of this metal. We have analyzed these samples and the results indicate that they do not contain other metals detectable by SEM-EDS. These specimens are already a few years old.


Size: 6.2 x 4 x 3 cm.

RM3014   Baryte

Clara Mine, Oberwolfach, Ortenaukreis, Freiburg, Baden-Württemberg, Germany

Grube Clara baryte specimens are a classic for the species in Europe. In this specimen we can enjoy numerous crystal aggregates, some isolated, presenting a rich complexity of facets. They are mainly formed by faces of orthorhombic prisms and curiously some are translucent while others are totally transparent. The brilliance, transparence and contrast on the matrix add aesthetics to this specimen.


Size: 7 x 4.4 x 2.5 cm.
Main crystal: 7 mm.

RM2999   Pyrolusite and manganite

Gremmelsbach, Triberg im Schwarzwald, Freiburg, Baden-Württemberg, Germany

A novelty from Sainte-Marie-aux-Mines 2022. These specimens come from a recent find in this mining area of the Black Forest and are reminiscent of those found decades ago in this area. They show radial aggregates of extremely brilliant pyrolusite crystals that partially replace manganite. By X-ray diffraction we have been determined the presence of both species, even with a certain predominance of manganite. They usually appear on a matrix of pink granite or as groups of large crystals in parallel growth. In the specimens we can observe the inclined flattened terminal faces. They are highly aesthetic pieces those will become part of the best specimens of these species for European mineralogy. We will send the XRD to the buyer.


Size: 8.8 x 7.4 x 5.2 cm.
Main crystal: 4.2 cm.
Found in 2021.

RM2937   Allargentum, safflorite and calcite

Wenzel Mine, Oberwolfach, Ortenaukreis, Freiburg, Baden-Württemberg, Germany

These German mines have produced some of the best specimens of silver and allargentum from European mines. A good-sized piece, we can see aggregates of this silver and antimony species showing rounded forms. Disposed very aerial on a calcite matrix. With good luster and bronze reflections. With safflorite. It belongs from a Spanish collection, and we will send the handwritten label to the buyer.
