is HCA useless for Emerald Cuts?

[psyflyer]

does HCA estimates only work for round diamonds? And is there any method to determine potential light return, fire, scintillation and spread for Emerald cuts?

HCA is for rounds. We have heard that AGS, who was the first to create a cut grade for Princess cuts is hard at work on cut grades for other square cuts such as emeralds and asschers next. Best bet is to post what you're considering wthl all measurements and an IdealScope to see if there is light leakage and those who are more knowledgeable about the cuts you're considering will offer their best advice.
