Haidingerite and Erythrite crystals from the Wilhelm Mine, Richelsdorf, Germany, Gerd Tremmel collection – small cabinet specimen as unique piece
This cabinet specimen with Haidingerite and Erythrite crystals originates from the Wilhelm Mine near Richelsdorf in Germany and is part of the Gerd Tremmel collection. The specimen displays an elongated overall shape with a striking color contrast between the vivid pink Erythrite crystals and the lighter, finely textured Haidingerite formation. The crystals are clearly developed and distributed across the matrix, creating a dynamic surface structure with strong visual impact. The combination of intense coloration, distinct crystal formation, and well-balanced specimen shape gives this cabinet specimen strong collector and display appeal.
Geology & Origin
The Richelsdorf mining district is a classic German ore field characterized by complex hydrothermal mineralization. Haidingerite and Erythrite form here as secondary minerals in oxidized cobalt and arsenic-bearing deposits. The Wilhelm Mine is especially known for its vividly colored Erythrite occurrences, which together with rare arsenates such as Haidingerite produce mineral specimens of high aesthetic and scientific interest.
