Calcite

This piece is quite unusual for the locale. It has a greenish caste and many modifications to the rhombohedral structure. Most notable are the definitive striations at the terminal faces, looking almost like hieroglyphs! Complete save one area of contact from another crystal. Ex Kay Robertson and ex Kenny Gay collections.

Locality: Pallaflat Mine, Bigrigg, West Cumberland Iron Fields, Cumbria, England
