Thermal etching post-crystallization adds a layer of complexity to this set of cubic Fluorite crystals with just a little Sphalerite on the reverse from the legendary Elmwood Mine. Internal color zoning and near-complete translucence make this small cabinet specimen exceptionally displayable. Elmwood Mine, Carthage, Smith County, Tennessee, USA. No longer producing specimens. 2.5" x 2" x 1.25", 3.7 oz.
