A museum-grade specimen of the rarely occurring manganese sulphide mineral, Alabandite, from the Uchucchacua mine in Oyon Province, Peru. This remote gold-silver-lead mine has produced some of the best crystallised Alabandite in the world. This specimen is composed from well developed octahedral crystals of up to 1.9 cm on edge, of dark graphite-grey to black and with a metallic, slightly waxy lustre. Some of the crystals are twinned with well defined re-entrant angles. Patches of fine-grained sucrosic Quartz nestle between some Alabandite crystals adding to what is already a magnificent specimen of this unusual sulphide species.
