What would be the ideal Depth for a princess w/ table 70.6%

The depth on a stone with that table width is not going to make a huge difference. A table of this size, though common for princess cut, is largish. It will restrict dispersion and some of the scintillation. A princess cut can look very nice even with these limiations, but it won't be a top performer in all respects.
