Rosell Minerales

Bementite is a very rare manganese silicate, identified in the well-known Franklin mine (NJ, USA), where it has its type locality. This specimen comes from a mining area located in the central zone of the Pre-polar Urals, known for the manganese, rhodonite and magnetite mines. In this specimen we can observe aggregates of crystals with golden tones that stand out on the matrix. An opportunity for systematic collectors.
