An astonishingly dynamic piece. Iridescent Chalcopyrite in many hues dot the Dolomite crystal covered surface of the entire specimen. This is the canvas the interestingly bifurcated crystalline presence of nicely terminated Calcite and Galena, each keeping to their own hemisphere of the piece.  Many of the Calcite crystals are beautifully and dramatically perched. Reynolds County, Missouri, USA. 5" x 3" x 3.75", 1.15 lbs.
