 Incredible two generations aggregate  of Calcite crystals. First generation of dark and opaque calcite crystals up 11 cm long covered with palygorskite and romanèchite.   Large twinned (fish tail) and single skalenohedrons of the first calcite generation are coated on front faces with white palygorskite and on sides and backs with romanèchite, the black manganese oxide. The first dark calcite generation enriched with manganese strongly fluoresces red in long wave UV, the second  translucent calcite generation partly fluoresces light violet. Huge contrast between snowy white palygorskite and deep black romanèchite with the second generation of colorless partly translucent calcite crystals on the top of the first one create a spectacular and exquisite specimen.
