Mineral: Aragonite
Locality: Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Dimensions: 5.0 x 6.7 cm.

Description: Pseudohexagonal aragonite with pyramidal white terminations and yellowish prism faces. Small cerussite crystals are present on the back side. According to the label this is a zincian-rich variety known as nicholsonite. I plan to get this piece analyzed to find out if that is true.
