Proportion question...

[bigterpsfan]

I realize that as you improve on the 4Cs the diamond gets significantly more expensive, but if you have a diamond with the same exact Cs, but one has proportions that are typically viewed as ideal does the price go up? In other words, do crown angle/height, pavilion angle/depth, lower half, stars, table %, total depth percentage, and measurement affect price significantly, all else equal? Thanks!

Each lab that grades cut has a different set of proportions/specifications that constitute each cut grade, and as cut grade betters the price increases. There is no "ideal" set of proportions for an RB - tastes vary, and even then how those numbers are calculated and reported is a significant source of error. I don't imagine you would have much luck trying to negotiate a lower price for a "leaky GIA EX", for example
