Good Table and Depth Percentages?

[motifone]

Hi all

I''ve been reading over the diamond education sections.

Is there a percentage range that is considered better than others? Or a percentage for table and a percentage for depth that makes for a better cut? When I see these percentages on a cert, how do I interpret them?

Right now, looking at princess cut stones.

thanks

Check it out! and Good Luck!
