We purchased a diamond the other day which we are seriously thinking of returning. It's a 1.5 ctw Princess Cut., H color, VS2. It's a Leo. In the store, the diamond looked beautiful. We looked at it under the scope at 10X and 30X and saw no carbon spots. In fact, it looked good to us. The symmetry was "good" and the polish was "good". However, when we left the store, out and away from the spot lights, we noticed what appeared to be an almost perfectly round circle of dark seeds or dots in the center of the diamond. In the brightest of light they fade, but in a regularly lit room, they are pretty noticeable - what is it that we are looking at in this diamond?
Thanks for your help.
