1st set arrived and had visible imperfections in the stones.  The surface was fine, it was something within the stones themselves.  The box was dirty too so maybe it was a previously returned set and they tried to drop it on me?  Not sure... Returned and bought another set.  Taking into account the price I paid, $249,  I am pleased with the 2nd set and will be giving to my girlfriend for Christmas along with a matching pendant.
