Fluorite, Sphalerite
Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA
Small Cabinet, 5.6 x 4.8 x 3.2 cm
This is a cluster of fluorite crystals from the now-closed Elmwood Mine that is UNUSUALLY transparent. In fact, they (also unusually) show marked zoning, with darker purple towards the outside. They have the shiny "pebbly" surface you sometimes see on fluorites from here. There is just a bit of accenting sphalerite. The crystals measure to 2.5 cm along the edge.
