A fine and uncommon combination specimen from the historic mines at Trepca, Kosovo and the Jaime Bird Collection. A pretty and well-placed cluster of translucent, lustrous, fat, tabular calcite rhombs is perched atop a matrix of smaller calcites, which are richly and aesthetically sprinkled with golden chalcopyrite microcrystals and radial sprays of quartz needles. All of the calcite crystals are tinted gray by inclusions of boulangerite, which is very uncommon from Trepca. Outstanding and classic combination material from this classic locale. Essentially pristine.
