- Small Cabinet, 7.5 x 5.2 x 3.3 cm
- Hercules Mine (Negra Mine), La Negra, Mun. de Carmargo, Chihuahua, Mexico
Spectacular, gem-like calcite scalenohedrons richly and aesthetically cover a bit of matrix on this beautiful calcite specimen from a very less well-known Mexican locality - the Hercules Mine in Chihuahua. The striking, large, 5.4 cm crystal on the left side is doubly terminated and twinned. Ex. Dave Stoudt Collection.
