Hello All!
I am very curious to know if the GIA measurement of the crown and pavilion angles is truly accurate. I recently purchased a diamond. I'm very happy with my purchase. It's measurements are:
55% Table
61.9% Depth
35* Crown Angle
41* Pavilion Angle
When I use the HCA tool, i get this chart 1. When I change the pavilion angle to 40.8, chart 2 is completely different. Which makes me wonder if a diamond can lose so much of it's performance from a mere .2* change.
Looking forward to hearing your input. Thank you.
