Gemmy, glassy, colorless, spear-like crystals to 1.0 cm in length, are surprisingly rich on this specimen. If not for the weight of the piece, you might at first guess calcite or smithsonite but not anglesite, which is so rare from Tsumeb! But they are indeed anglesite, flanked and surrounded by botryoidal spheres, to .2 cm across, of a dark gray to black, mineral, possibly one of the manganese oxides. Unusual!
