Celestite is not a stone that is tumbled often, as it is very soft. This material, coming from the deserts of California, is tougher than most material, so it is great to polish or tumble. You can even polish the material further, as this tumbled material is polished, but not hand polished, which gives the best results. http://www.gemsnail.com/Tumbled-Stones/155/one-pound-of-TUMBLED-CELESTITE
