The experts say GCAL images don't say much individually, but I still wanted to hear some thoughts/comments on how these 2 sets compare.

Optical brilliance analysis image
A
has more dark spots on the outer ring so does that mean more leakeage? B has less dark spots but then they look imbalanced (less dark spots on the left half). Is that indication of imbalanced symmetry?

Optical symmetry analysys image
A
's picture seems to have more contrast and is aesthetically more pleasing. Is it any better than B in terms of optical symmetry?

Hearts
A
seems to have more distinguishable, balanced hearts. Does it have a higher chance of being a genuine H&A?
[Edit] From ff's post on a BN diamond seems like the hearts photomicrograph is *not* a good indicator! The hearts from the GCAL report didn't come out that well but the pictures he took from H&A viewer are amazing!

The cut precision for a h&a diamond which upholds the standards as decreed by h&a experts is extremely strict and without better hearts images no way to judge overall cut precision regrettably.

Your over analyzing the images they arent good enough to draw the conclusions your drawing.
They are only good enough to show that there are not any gross anomalies with either diamond.
If you want precision images find a different vendor.
