Black platy crystals of the copper-manganese oxide, Crednerite, are intermixed with black sooty manganese oxides from a manganese pod with included platy white Calcite. This specimen is from the famous Torr Works quarry at Cranmore, near Shepton Mallet in Somerset, England; more commonly known to collectors as Merehead quarry. The Crednerite blades are up to 3 mm in length and stand out from the manganese rich matrix because of their bright lustre.
