Snow white crystal groupings of calcite to almost 4.0 cm in height coming nicely off matrix. In great condition. The Boldut Mine, situated in the Cavnic mining district of Maramures County, Romania, is part of a historic polymetallic extraction center with roots dating back centuries. Geologically, the deposit lies within the Neogene volcanic belt of the Eastern Carpathians, where complex hydrothermal vein systems cut through volcanic and sedimentary host rocks. These epithermal solutions deposited rich concentrations of lead, zinc, copper, gold, and silver ores. Beyond its industrial mining history, the Boldut Mine is internationally famous among mineral collectors for producing magnificent specimens of quartz, rhodochrosite, and carbonates in association with various sulfide minerals such as pyrite, sphalerite, and galena.
