This small specimen consists of several pyritohedral Cobaltite crystals that are embedded in a matrix that itself appears to be made of a metallic mineral. One crystal in particular is exposed, and it appears to be the only one that shows any damage, which is minor. It measures 0.2" (5 mm) in diameter and shows excellent form, with well-defined edges and clean faces that possess a bright metallic luster. It has the standard silvery-white color of Cobaltite, and somehow I get the feeling that the matrix itself is made up either of more, massive Cobaltite, or a closely-related metallic sulfide.
