Large sharp pseudo-hexagonal crystals of pyrrhotite measuring to 4.0 cm in size across the top of matrix with quartz. Excellent example for the species from the locality, in great condition. These are likely in the process of being replaced by crystalline pyrite.The Herja Mine, located in Maramures County, Romania, is a historic underground mining site with centuries of activity focused on base and precious metal extraction. Geologically, the deposit is situated within the Neogene volcanic belt of the Eastern Carpathians, where complex hydrothermal veins cutting through sedimentary and volcanic host rocks formed rich epithermal orebodies. The mineralizing solutions deposited significant quantities of lead, zinc, and copper sulfides alongside gangue minerals. The underground stopes and vein systems are internationally renowned among mineral collectors for producing crystallized specimens, most notably large, well-formed groups of stibnite crystals associated with quartz, sphalerite, semseyite, fizelyite, etc.
