Colorless scalenohedral crystals of calcite across an andradite with quartz. Nice combination piece from this old classic European locality. In great condition.Ocna de Fier, located in the Cara--Severin County of western Romania, is one of the oldest and most historically significant mining districts in Eastern Europe, with iron and polymetallic extraction dating back to Roman antiquity and experiencing extensive commercial operations through the Austro-Hungarian period into the modern era. Geologically, the area is characterized by a classic skarn deposit where Cretaceous granodiorite and banatite intrusions invaded older Jurassic limestone and metamorphic sequences, creating intense contact metamorphism. Mineralogically, this complex geological setting fostered the formation of an exceptionally diverse array of over one hundred mineral species.
