Chalcostibite is a rare copper, antimony sulfosalt. This fine combination piece from the Boldut Mine of Romania features shiny, gray metallic blades and needles of chalcostibite clusters scattered on lustrous tetrahedrite crystals and associated with zinkenite, quartz and calcite. Chalcostibite was never common at Cavnic and this major discovery was made in 1990.
