after reading all the interesting replies on brilliance , it seems to me that in order for me to stay within my budget , $2000 ,for a princess cut,i either have to sacrifice some better prefered depth and table pecentages for higher ones, high 70's to low 80's and thus loose some brilliance and light reflection or go down in carrat weight and keep the better mid 70% TABLE AND DEPTH PERCENTAGES ? am i on the right path ??? in the end i'm not so worried about evaluating numbers so long as at the end of the day i have a great diamond for the money i spend and has good brilliance , fire and light reflection , should i come down in carrat weight and strive to get better table and depth percentages , will that give me better brilliance ??
