Semseyite is an uncommon lead, antimony sulfosalt, seldom found in well-formed crystal groups such as this. This is a superb, complete all-around and pristine cluster of sharp sprays of lightly iridescent, metallic-luster semseyite blades on sphalerite matrix. From near the Type Locality. Ex. Ed Ruggiero Collection.
