Im trying to get my stone set before the big proposal next week and keep getting mixed information. So if anyone can help I would greatly appreciate it. My setting has a peg head, 1ct-1.5ct (6mm to 6.5) my stone is .81ct (5.93x5.97). One jeweler says I need a new peg head, its too big. One say it will work. Any advice would help, thanks so much!
