An AMAZINGLY, COOL-LOOKING specimen of olive-green mottramite coating lustrous, milky-white calcite rhombs to 3.0 cm from Tsumeb. The neat thing about this piece is that the dominating, large crystals at the top have mottramite CRENELLATIONS on the crystal edges! Very trivial damage overall to this very showy and fine Tsumeb specimen, which is viewable from either side. 7.0 x 4.1 x 4.0 cm
