Comment: A classic and very showy combination specimen from the famous Nchwaning II Mine of a large field of variable-length acicular kutnohorite crystals. A curtain or wall of matrix separates the kutnohorite from a vuggy cluster of botryoidal manganoan calcite at one end. A striking, distinctively separated combination specimen, which includes this uncommon carbonate.
