The slight leakage around the girdle is pretty standard for ideal cut stones, and many people feel that -as long as it's slight like here- it can enhance the 'on-off' sparkle effect along the edge, a good thing. The white points in between the arrows remind me of the Venus by Infinity stone I looked at, which was to die for.
Again, looks like a fantastic stone. What are the rest of the specs?
I believe that IS image may be JUST barely off plum for that stone... alternatively there could be a slight slope to the crown.... is it possible to post the hearts as well... it looks like it has outstanding symmetry (if I am correct on my first assumption).....
