This specimen features beautiful sharp ankerite crystals with pyrite crystals. The ankerite crystals are sharp, lustrous, and exhibit an extra modification face, unlike the ankerites from here that are commonly simple rhombohedra. The pyrite crystals are sharp dodecahedra with a small number of brilliant tiny triangular octahedral faces – this could just easily be considered a specimen of pyrite with ankerite, as both minerals are prominent and equally good. Some minor siderite in association as well. in excellent condition, a couple of incomplete ankerites at the periphery. A great piece!
