Pyromorphite crystals from the Müsen Mine, Siegerland, Germany, Gerd Tremmel collection – miniature specimen as unique piece
This characterful miniature specimen displays several rounded to flat aggregates of brown Pyromorphite on a dark, fine-grained matrix. The crystals form dense, velvety-looking coatings with a clearly crystalline structure. On closer inspection, numerous small prismatic crystal tips are visible, giving the surface a subtle sparkle.
The warm brown to chestnut tones of the Pyromorphite contrast attractively with the grey to dark green matrix. The crystals are clearly developed and evenly distributed across the surface, creating a balanced and aesthetically pleasing overall appearance. A typical and highly collectible specimen from a classic German lead deposit.
Geology & Origin
The Müsen Mine in the Siegerland district is one of the historically important lead and zinc ore deposits in Germany. Pyromorphite forms there as a secondary lead phosphate mineral in the oxidation zone of primary lead ores such as Galena. Through weathering processes and the circulation of phosphate-bearing solutions, Pyromorphite crystallizes in fractures and cavities of the deposit.
Occurrences in the Siegerland are known for a wide range of colors from green to yellow and brown. Specimens from the Müsen Mine hold a firm place in many collections due to their historical significance and classic mineral association.
