An excellent and showy specimen of floater, cyclically-twinned, gray cerussite crystals altering to hydrocerussite, showing partial alteration on the outside of the cerussite, from Tsumeb. The end-on shots highlight the intricate twinning of the crystals. Very minor edgewear is certainly not detracting from such an uncommon Tsumeb mineral in good crystals. 3.6 x 3.5 x 2.2 cm
