This large hand specimen consists of a cluster of large, heavily-intergrown and warped Sphalerite crystals that rest on a limestone base. Many are heavily damaged or broken, but several are intact. These crystals appear to measure up to 1.2" (3 cm) along an edge, though twinning may give them their large size. Even with their intergrowth and twinning, the larger ones still have a moderately good, though considerably warped form, with some well-defined edges and a few flat, clean faces. All have the dark brown coloration and adamantine luster that one expects in Sphalerite from this locality. They are accompanied by countless small, white dolomite crystals that coat the dolomitic limestone base.
