A superb miniature sized specimen and among the really good ones went through my fingers over the years. A beautiful 3-dimensional piece with sharp roman-sword-shaped crystals of rare sulfide Semseyite, perched on jet-black metallic Sphalerite matrix. The crystals are excellent defined and super terminated. Semseyite is an uncommon lead, antimony sulfosalt, seldom found in really well-formed crystals, but these are super-formed, and the specimen comes from the type locality, the Baia Sprie Mine of Maramureș. An elegant mini with only minor imperfections .
