Sigulani Village, Tambani Area, Blantyre District, Malawi
A brown (or gray/brown in certain light) somewhat rounded, striated, single crystal, with a broken terminal end. We got almost two tons of this material in 1968, and culled some of these crystals from the bulk tumbling grade. There are more available, smaller sizes, if you are interested in an email quote.
