Chalcopyrite on Quartz Matrix Specimen
This is a striking specimen of chalcopyrite perched atop a quartz-rich matrix, accompanied by a second dark metallic crystal likely goethite or oxidized chalcopyrite. The chalcopyrite crystal displays a bright golden metallic luster, excellent striations, and sharp geometric faces. The secondary crystal provides beautiful contrast in both color and texture, creating a bold and dynamic display piece.
This specimen comes from a Chinese locality known for producing sharp, isolated chalcopyrite crystals with minimal matrix clutter. The white crystalline base enhances the metallic sheen of the minerals and brings out their natural geometry.
