A genuine Ural topaz of natural colour. The crystal fragment was bought from a former geologist of the Neivo-Shaitn geological party. See the separate video of this fragment. The stone really differs from ordinary irradiated topazes. There is a very unusual GZhV inside, though it is visible only under a magnifying glass. There are no cracks, of course.
