I recently purchased a .825 ct G vs2 from Whiteflash http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-2763663.htm. The order is being fulfilled this week, so the diamond hasn't been set yet on the setting I picked out. After making the purchase I noticed that they received new inventory, one being an 86 point F eye clean SI 1 http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-2794544.htm . Is it worth considering paying a little more to upgrade the size and color? I like the idea of being closer to that 1 ct mark, but am not sure if there is much a difference in the two stones. What do you all think?
