A great cluster of super gemmy Rockcrystals from the Sellenentobel at Etzlital of Maderanertal in Uri Canton, Switzerland. The crystals here are showing outstanding clean quality. They are razor sharp and superbly terminated as well. Luster and integrity are excellent as well despite that one of the smaller crystals has an imperfection. This kind of material is hard to come by nowadays and even the Strahlers are asking for crayzy numbers.
