Hi everyone, this site is really a useful resource. Thanks to all who contribute.

I've seen Dave Atlas's AGA chart for princess cut diamonds, however, I'm curious if there are 'ideal' crown and pavillion angles for princess cuts as well. I think I've seen somewhere that you want a crown angle on a princess cut of 31-33 degrees, however, I can't recall where I've seen this. Is it accurate?

Thanks

Princess Cuts and fancies are very difficult to gauge by
the numbers. You need to see them; and if you're
shopping on the Internet, you need some form of visual
data to show you the diamonds light performance.

The fact is there are various combinations of
Crown/Pavilion/Table that will yield high
light-performing Princess Cuts.

The best tools we have found so far are the
BrillianceScope and ImageScope which
measure both light performance and light leakage.
The numbers, thus far, are secondary.
