RM1722   Manganocalcite with fluorite, galena and pyrite
Ca(CO3)
  -  5. Carbonatos y nitratos

Very esthetic specimen formed by numerous aggregates of crystals of calcite manganoan, very bright, transparent to translucent, forming globular groups very well set on the matrix. They present a slightly pinkish tone due to the presence of Mn. Extremely fluorescent under LW-UV, with a spectacular pink to red color. They are accompanied by small octahedral cubic crystals of colorless and transparent fluorite. In a matrix of bright crystals of pyrite, sphalerite and galena. An exceptional piece. 332k1d
