So now im a bit confused... I wanted to see what was in the "ideal" listing on jamesallen.com, since this entire time i''ve been searching for AGS0 and/or H&A listings only, basically only the premium selections. I found a diamond that was not listed as H&A, but still had ideal cut, and HCA''d very low, with excellent on everything. My question is, how does a diamond measure up exceptionally well, but not pass H&A muster?
