Not impressed at all with these. I understand that when working with a natural product things will vary greatly, but I still expected something that looked comparable to the listing picture. The ones I got have a faint ring of blue at the edge, the rest is pure white. Well, except for the dried blue dye that's on the outside of the stone. They clearly took the best looking one from the bunch for the photo. Again, not impressed.
Very little blue color, smaller than expected, not impressed
