TitleSemseyite
DescriptionSemseyite, Pb9Sb8S21 (lead antimony sulfide), forms interesting aggregates of intergrown tabular crystals that are rather unique. Semseyite is another rare sulfosalt, a segment of sulfides where the antimony acts more like a metal than a non-metal and occupies a position where it is bonded to sulfurs. Semseyite is also one of several lead antimony sulfides, an informal group of similar minerals.
