Great gift idea
Way nicer looking in person than in the photo. The blues range from a nearly clear blue topaz to a rich royal blue. Some of the coasters had very brilliant crystal structures embedded in them.  Polish was nicely done and should hold up to daily use. Gift box was nice and packing was very secure against breakage during shipping. These are a good alternative to the usual ho-hum coasters you find everywhere. I purchased these as a gift for a rock hound friend of mine and she loved them.
