by virginia1 » Apr 2, 2002 Should I be concerned about the girdle thickness of this diamond? How thin is thin enough to worry about chipping? I am trying to decide between this an a great 1.18 that I found--that is about $400 more, AGS-O. (This is GIA certified). Will the difference in diameter (6.66 v. 6.84) be noticeable? I'm going to try to go to a local store and see if I can find similarly sized stones to do size comparisons. Thanks again--you all have been an incredible help!
