At least 7 Spinel octahedrons rest in the white host rock of this hand specimen. These crystals generally do not exceed 0.1" (3 mm) in diameter, but one is much larger, having a diameter of 0.3" (8 mm). Most are in excellent condition, showing no damage, but one or two are visibly damaged, and one is mostly incomplete. Their octahedral form is excellent- all have well-defined edges and clean faces that possess a rather dull, pearly luster. Their color is a rather dull, deep violet, and only the smaller crystals are visibly transparent. The largest crystal shows patches of shallow transparence, but is moderately to dimly translucent as a whole. They are accompanied by several small and generally incomplete muscovite books that have a pale brown color and are impressively clear. The host rock in which all of these rests is quite calcareous, though I believe that it contains a substantial amount of feldspar.
