Thanks for the info. I've seen the site before, and the main problem here is that the information doesn't take into account GIA rounding. For example, based on this 35/41 is listed as do not work. For a simple example of how it cannot be directly applied to GIA certs, lets take whiteflash whose ACA, a super ideal cut, usually cut to 34.9/40.9 angles, occasionally even over as that is the look they are going for. If graded by GIA, this would be 35/41... if this could not be hearts and arrows, well over 50% of their ACA would not be hearts and arrows, a very very unlikely scenario.
And based on the site (not just the table but the content below), bro banbanz diamonds still all seem within H&A range... In addition, although GIA has rounding, JP visual inspection and selection process should have ensured that it was on the right side of the rounding. Which means the only thing left to look out for would be optical symmetry.
Yep, agree with both points ! Congrats on your ring and your good experience
