Best Depth,table Spec For Cushion Diamond?

Alfonso Hui

Recommended Posts

Is there a way to gauge how a cushion diamond will sparkle by looking at the depth, and table? or any other information from a GIA grading report? I purchased a GIA cushion modified brilliant diamond from James Allen, and I was slightly disheartened by the lack of brilliance and scintillation (in a word, it looked dull). Is there a way to pick a better one without breaking the wallet of retail price? Thank you.


Also, is there a way to tell from a GIA report if a cushion diamond will have the crushed ice look, or the traditional radiant look?

There is absolutely no way to tell from the lab grading report. "Numbers" in fancy shape diamonds are absolutely non-predictive in telling you how the stone will face up because light entry/exit is haphazard due to the irregular archircture of the stone. Thus two cushions with the same exact "numbers" can look diametrically different.


Two things you need to do:


1. Specify what kind of look you want.

2. The Vendor needs to personally review and evaluate the diamond. Supplying photos is helpful.
