Dyscrasite crystals from St. Andreasberg, Harz, Germany – small cabinet specimen as unique piece
This cabinet specimen shows Dyscrasite crystals, polished section, from St. Andreasberg, Harz, Germany, and comes from an old collection with a historic label. The polished surface reveals the internal structure of this silver rich mineral and highlights its characteristic metallic areas particularly well.
The Dyscrasite crystals are visible and form flat compact crystalline areas with a strong metallic luster. Notable are the vivid tarnish colors in blue violet gold and reddish tones formed by natural oxidation processes. This colorful iridescence gives the specimen an exceptionally vivid and decorative appearance.
