Excellent truncated edged rhombic crystals of Calcite from the Tankerville Mine, Shelve, Shropshire. The mine along with the Snailbeach Mine was one of the most productive in the area, although we very seldom see specimens from the Shropshire mines. On this specimen the Calcite crystals measuring to 1.6cm have formed on bright metallic grey crystals of Galena. Crystals of Calcite are translucent-opaque white with great luster. A bright uncommon specimen from the mine.
