Two small complex Galena crystals sit to one side next to a larger and cleaved cubic Galena crystal.  From Clausthal-Zellerfeld in Harz, Lower Saxony, Germany, the Chalcopyrite forms a thin 0.5 mm coating over the gunmetal-grey Tetrahedrite crystals; the Chalcopyrite is a speckled, golden-brass colour displaying slight iridescence.  The Siderite has a bright silky lustre and is peppered with 1 mm, creamy-translucent curved blades of Dolomite.
