Thin platy mostly gemmy crystals of barite measuring to 2.0 cm in size forming a cluster without matrix. Note that the specimen is half black and half yellowish. The black color due to inclusions of jamesonite. Minimal cleaving present, this still in good condition all around.Baia Sprie, historically known by the Hungarian name Felsobanya, was first officially documented in 1329 and developed into a major medieval mining center for gold, silver, and base metals under Hungarian and Habsburg administration. Large-scale underground and surface mining operations continued for centuries until the active commercial exploitation of its metal deposits ceased in 2007. Geologically, the area is situated within the Neogene volcanic chain of the Gutai Mountains in the Baia Mare metallogenic district. The local geology is characterized by complex Neogene volcanic structures cutting through sedimentary and metamorphic basement rocks, hosting world-renowned hydrothermal vein systems rich in diverse polymetallic sulfide and precious metal mineral assemblages.
