Very clear Calcite crystals with red inclusions of Hematite. The Calcite has a high luster and with the many faces, the specimen sparkles. There is a diagonal band of black under the Calcite in the middle of the specimen. This is likely a Manganese mineral. There is also a small area of yellow material at one end of the specimen which is likely Sturmanite or Ettringite. The specimen is very attractive and in good condition. The crystals are without damage except at the end where the yellow material is.
