A cabinet specimen of rare black alabandite from the Uchucchacua Mine in Peru. While this mine is best known for its rhodochrosites, silvers, and silver minerals, around 2010 it also produced (what were then) some of the finest examples of this black manganese silicate. Interestingly, around the same time, there was also a discovery in Merelani. Most of the crystals this specimen seem to be twins, as was typical for specimens from this find (though interestingly, not from. other localities)
