Superb smoky quartz crystals in a wonderful cabine sized cluster. Needless to say, this piece comes from the famous Rufibach pocket in Grimsel area, the quality speaks for itself! It has not been surpassed for decades, and still sets the standard for any smoky quartz crystals in the world. There is one little chip (about 2mm wide) present on the crystal tip, it goes to the back side and is barely noticable from the main display angle. The aesthetics and composition of this piece are truly amazing!
