Apply to all shape of stone. To fancy shapes, like pear or cushion, not that many ideal cut (depth=60%), 62-66% still concidered very good cut, but it's the best if you can find one around 62%, definitely if >70% it will be bad.
thank you, I want to buy a cushion style stone, but there's not that many choices out there.
