Recently purchased a diamond waiting for to arrive in the setting, I thought I researched and researched but alas double and triple checking while waiting I am worried what I purchased might be too "steep and deep". Hopefully with gia rounding and the 80% lower girdle leakage wont be too bad? HCA on it scares me, I would ultimately like to keep it and not return it but if I completely messed this up returning is something I will strongly consider. Originally I had looked at a larger cushion cut but viewing round diamonds in person the brilliance vs cushions flipped me. I thought if I went off "ideal" dimensions I would be safe for brilliance but I am starting to think I put too much trust in gia xxx. My original intent was to go for brilliance over size. Either way any help is appreciated and thank you in advance.
