A cluster of pitch-black ferberite crystals that have small arsenopyrites here and there. The ferberite crystals are bladed with dull-black luster and very sharp faces. Interestingly, the arsenopyrite crystals all have a ring of a yellow alteration product around them-scorodite? Not perfect but excellent for this mineral.
