Two adjacent Sphalerite clusters rest on the gray limestone base of this hand piece. The larger cluster is made up of several heavily-intergrown Sphalerite crystals that are in good condition and do not appear to exceed 0.5" (1.3 cm) in diameter. All show very warped tetrahedral form. The other cluster might actually be a single crystal- it has the triangular shape of a tetrahedron, though it is flattened (see the second image). All have a dark brown coloration and an adamantine luster, and show dim transparence along their edges when examined under bright light. A single, tiny violet fluorite cube rests nearby.
