The price per carat on the white flash diamond is 9666/carat and the good old gold is 10927/carat. Is the good old hold a better cut diamond or is that price difference normal for a .3 increase in size. Will you even be able to tell?

What about the girdle between the two? Any expertise help would be appreciated.
