A spectacular display piece of sphalerite, pyrite and chalcopyrite from Trepca mine in Stan Terg, Mitovica, Kosovo. This sample features sphalerite crystals and pyrite cubes on a chalcopyrite base, it also shows minute inclusions of botryoidal dolomite and calcite blade crystals. This creates a beautiful metallic aesthetic as the black sphalerite crystals and grey/brassy yellow pyrite cubes have formed together showing a fantastic change in colours and habits. The sample weighs roughly 758 grams and measures approximately 11 x 6 x 5.5 cm, it is supplied in a 5" x 3.5" white card tray with an information label. This is a must have specimen for any mineral collection as it shows a wonderful array of lustres, habits and colours and is sourced from a location that is difficult to access.
