Multi-specie specimen with at least 8 minerals present, the most significant being a cluster of Semseyite from this type locality. This is a complex matrix holding milky Quartz crystals that are surrounded by Siderite and Pyrite. Semseyite in radial form sits on one edge and Galena, Sphalerite, Chalcopyrite and Dolomite are evident too. Baia Sprie is the type locality for Semseyite, but it was more more commonly found at Baia Mare. Semseyite is fairly rare at Baia Sprie. Long known as Felsobanya, this locale had been mined since the 14th century, so by any definition the locality and this specimen are classics. The mines have all been closed since 2006. Ex Ernie Schlichter, this is a good example and especially interesting with magnification.
Very well formed, large (to 4 CM across) rosettes of sharp and lustrous Semseyite in undamaged condition. The matrix is a mix of lustrous black Sphalerites and Sphaerosiderite balls colored by Boulangerite. A few Chalcopyrites sprinkled in add a little extra color. These are the biggest undamaged osettes we have handled, the overall esthetics is very strong and fine for the specie.
