Two very large and rather warped Sphalerite crystals rest on the dolomitic limestone base of this piece. Each of these crystals appears to be made up of more than one crystal that are heavily intergrown with each other, and one shows definite twinning. Both are in good condition but show some minor damage, and both have a badly warped tetragonal form that appears nearly sphenoidal, with disjointed and sometimes slightly curved faces. Even so, their edges are well-defined. They have the standard dark brown coloration a bright, nearly adamantine luster, and are essentially opaque. They are accompanied by a druse of tiny, transparent quartz crystals and a few white dolomites.
