Hureaulite & Rockbridgeite

Jocao Mine, Galileia, Minas Gerais, Brazil


Complex specimen with well crystallised pink Hureaulite accompanied with a little Rockbridgeite. Excellent hureaulite crystals for such a rare specie and little has come out of this famous manganese pegmatite deposit since the exceptional find in the mid 1990's. Additionally the specimen has a small area of individual tan coloured crystals that  look under the microscope like Stewartite - needs testing. Also blue-green stellate crystals around rockbridgeite nodules look like Beraunite.
