Elmwood Mine, Carthage, Smith County, Tennessee, U.S.A.
Another specimen from the prolific Elmwood Mine, this piece consists of a gray dolomitic limestone host rock on which rest several Sphalerite crystals. These crystals range in diameter from 0.2 - 0.8" (0.5 - 2.0 cm), and are sometimes difficult to define, as they are often heavily intergrown. Their tetrahedral forms are very warped, but only one crystal shows any sign of heavy damage. All have the deep brown color and adamantine luster that is common for material from this locality, and show patches of dim translucence/transparence under bright, halogen light. The host rock on which they rest is partially encrusted with tiny colorless quartz and white dolomite crystals.
