I am considering a diamond that's graded by GIA as Triple-ex. Even though this has HCA score of "1.6 - Excellent within TIC range", I am concerned that this doesn't have most common proportions in ideal grade of ~34.5 degrees for crown and ~40.8 degrees for pavilion.
Should I be concerned that this will be low on Scintillation, fire, brilliance and perhaps prone to chipping? I am considering prong setting.
Can any experts share their view? Thanks!
