Calcite, Sphalerite – Elmwood Mine, Tennessee, USA
 An impressive and aesthetically arranged collection specimen of calcite in the sought-after orange color on sphalerite. The highly lustrous sphalerite forms a beautiful base for the two aesthetically arranged calcites. The transversely positioned calcite is twinned. Both crystals are partially transparent with beautiful, intensely colored zones.
 Magnificent collection piece from the famous Elmwood Mine in Tennessee.
