Description: Large KMF rhodochrosite cluster on black manganese matrix. From an old collection. Once completely covered by a layer of calcite. Was worked on by Markus Walther a specialist in cleaning and trimming. Personally cleaned and trimmed by myself again to remove excess calcite and lose crystals at the peripheral.
