Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA 10.5 x 10.5 x 4 cm. This is an Elmwood specimen from the famous late 1970s "jewel pocket", that was recently traded to me out of the collection of the Benjamins, friends in France known for their exquisite taste in fluorite and calcite in particular.
