Like other fancy cut diamonds, the GIA does not grade the cut quality of Princess cut diamonds. For this reason, couples should note that any jeweler who advertises GIA-certified Princess cut diamonds with cut grades is offering their own opinion. In other words, the accompanying GIA certificate will not list a cut grade. Notably, there is also no industry standard for what constitutes an “Ideal Cut Princess Diamond,” either. However, there are certain specifications you can look for to help you choose a bright and brilliant Princess. We’ve put together the table below to help you evaluate cut.
Pro Tip! The most lively and beautiful Princess cut diamonds have good play between light and dark when rocked back and forth (diamond experts call this “contrast”). Yes, that’s right, you want some darkness in your stone! The main things are that you want it to be even throughout (not only in the center or in the corners), and not make your overall stone too dark.
