Beautiful silver-grey moonstone.  The colour is a subtle shade of smokey greyish-blue and makes me think more than anything else of Russian Blue cats; silver with a good dose of blue in it. Added to that is the pale silver schiller and the pronounced cat's-eye that shimmers across the stones when they catch the light.  Good clean cut, excellent polish, this is nice quality material.
