I found one site that explained the international cut grading for emerald cuts and I have looked at the price comparison at this site. When I look at the price comparison sheet here and prices of diamonds, they differ tremendously. I found things like: a 2B F-VVS1 stone, average price at $6644/Ct and a 3A F-VVS1 stone, average price at $6830/Ct. How can that be???Also, when I look at price list of vendors online, I can see two of the same characteristic diamond, except for cut and they don't follow the logic of better cut is more expensive.. I have seen that between 58%-69% depth and table are a 2A or 2B cut. Also, the percentages ar a wide range of numbers.Can someone straighten me out on the cut percentages of an emerald cut diamond??? What to look for in an emerald cut if I see 5 comperable diamonds?
