Just a random question: I couldn't really find it answered elsewhere: the diamond I purchased is a 1.4 FIC on the HCA scale:
62.4 depth %
55.5 table %
35.6 Crown angle
40.6 Pavilion angle
I assume those are "desirable" angles?
How does this differ in performance from a more typical sub 2 TIC on the HCA scale? More fire I take it, but at the expense of what? Overall brightness? And what kind of percentages are we talking: 5 percent more fire, 5 percent less brightness? Obvious, or subtle differences? I was only able to compare it to the Hearts on Fire diamonds, which didn't have published angles. When a diamond is cut, is there a reason it is cut with a bit larger Crown Angle that gives it an FIC rating? Does it depend on the diamond, the preference of the cutter, or is just random variance? Does one style carry a price premium or discount, or are they considered similar in quality? Just curious, thank you!
If it matters, here is the cert:
