I have been looking for a 1.5c princess ring. i have been trying to follow fred's 65/65 rule, but have not been able to find a ring with those measurments, except at Tiffany's. However I do not want to pay their price for the ring. Fred has offered to sell a ring to me. Just wondering if it would be wise to buy from him? Also, is it important to follow the 65/65 rule when buying a princess cut diamond? Thanks for your replies.
