I recently purchased a round GIA Lab, Excellent Cut, 1.01 ct, SI2 (100% eye clean, cloud did not make the grade), E color, and 1.3 on the HCA from James Allen. I am super, super happy with the diamond. Thank you so much to Pricescope on helping me to make an informed buying decision! There is so much information here!
Throughout my research I kept seeing where people would say that an excellent cut GIA or AGS 000 diamond will actually look like a larger stone than the same sized stone all other things equal when the diamond is only fair or good cut. For instance, I read discussions where people who had a .75 ct Excellent cut diamond in their ring would say that people would ask or assume that their diamond was over 1.0 carat because it looked so brilliant/big. I realize that spread can play a role in this because if a diamond is too deep it will look small for its size and if it is too shallow it will look bigger in some ways but will suffer in others.
Is there anyway to quantify how much ‘bigger’ a GIA excellent cut would look compared to a GIA fair cut?
What are your thoughts?
