- Sphalerite (Stalactite)
- Cabinet, 11.8 x 6.5 x 4.0 cm
- Elmwood Mine, Carthage, Smith County, Tennessee, USA
This specimen is composed of several, doubly terminated, blocky, splendent, black crystals, to 5.0 cm across, of sphalerite. The growth is reminiscent of a stalactite. Few trivial dings, only, and almost pristine. This is about the highest caliber you can find for the species at this mine with HUGE and well-formed crystals that are so black, they are almos tcolorful.
