Crystals of sharp golden large chalcopyrite just over 2.0 cm in size throughout a crystallized quartz matrix with dolomite. Crystallized black tetrahedrite is scattered throughout the surfaces of the chalcopyrite crystals. This is in terrific condition.Cavnic, located in Maramures County, Romania, is an ancient mining center with documentary records dating back to 1336, though local extraction activities date back to Roman times. The formal industrial underground mine modernly opened in 1958 and continued operations through various state-managed structures until its permanent closure in the early 2000s. Geologically, the deposit is situated within the volcanic Gutai Mountains, featuring complex hydrothermal polymetallic vein systems hosted in Neogene volcanic rocks. Mineralogically, Cavnic is world-renowned for yielding rich reserves of lead, zinc, copper, gold, and silver, alongside exceptional specimen mineralogy including striking blue barite, quartz, and various sulfide and carbonate assemblages.
