NA27AM0: Polycrystalline growths of complex Calcite crystals with dominant scalenohedral forms. On matrix, with transparent and shiny Fluorite crystals with an intense and uniform yellow color and coatings of cubic and lustrous Pyrite crystals. The specimen comes from the Villabona Mine, which has not produced many quality specimens and should not be confused with the much more prolific Solís Mine.
