What you see here is a rarity from Switzerland. It shows a beautiful colored smoky quartz with tunnels of anhydrite. The anhydrite was removed naturally so the hollow tube left in the quartz (photos 3 & 4). The crystal itself shows high quality with a nice color, great luster and clearity. It is developed as a floater.
