White bladed crystals of extremely rare Parafransoletite to about 0.3mm in size. The crystals are hard to see since they occur with Englishite, another white, but pearly mineral. The black is a Mn oxide and there is a little Montgomeryite (pink) and Roscherite. All the minerals occur on light green Beryl.
