Galena on Manganoan Calcite with Pyrite, Kruchev dol Mine, Madan District, Smolyan Oblast, Bulgaria Mined 2013, Small Cabinet 5.5 x 5.8 x 8.5 cm, $200. Online 6/9.
Highly complex, bright silver/gray galena crystal, 2 x 2.2 cm, on manganoan calcite with numerous associated galena and pyrite. The main crystal is dominated by the cube and modified by hoppered octahedron faces. There are also raised edges around the cube face and some etching and re-growth. In addition, the main crystal is slightly off on one side, ie., it is not 90 degrees which indicates Spinel Law twinning. A very intriguing and aesthetic galena from advance mining in 2013. In great condition.
