Hi, I just went to Bailey Banks and Biddle and was discussing a diamond that I was thinking about purchasing online and having set by them. When I showed the salesperson the cert for the diamond she said, "Oh this is an AGS certificate...their grading is much less strict than GIA so this diamond is probably a color of I or J (cert says H) and a clarity of SI2 (cert says SI1). Is there any validity to what she was saying? Please let me know. Thanks!
