Calcite with Jamesonite, Quartz, Siderite

specimen number:
2312098

location:
Herja mine, Maramures Co., Romania

description:
A neat and attractive elongated cluster of rhombohedral calcite crystals, these slightly dark in color due to inclusions of jamesonite. Small crystals of quartz and siderite are present as well. This is a floater with no points of attachment, in super condition all around. Classic material for this old and long closed locality.

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.
