Alabandite, Merelani Hills, Simanjiro, Tanzania

Most of us are long familiar with the Tanzanite crystals from the Merelani Hills. Similarly, many of us have seen the amazing diopside, graphite and pyrite specimens from there in more recent times. Another new development! At times, very sharp and relatively large alabandite crystals, a relatively rare manganese sulphide, are recovered from high graphite zones. I am fortunate to find a fellow who lives in Tanzania and was able to obtain some reasonable priced, sharp alabandite crystals from the Merelani Hills. The crystals are, normally half crystals. They were attached to matrix in calcite/graphite and when they become loose, they show attachment on the bottom or back of the crystals. They are pretty amazing for alabandite! Here are a number of very good examples.
