Since you seem to be implying that the stats I quoted are impossible or the diamond's papers are faked, I took a look on Blue Nile and
found this nearly identical diamond for a nearly identical price. Many others in the same ballpark in terms of the 4 c's and price. I think you probably do get more for your money from the princess cut because it's less complicated, etc. Also, I never claimed to be a diamond expert like you.
