by calla » Oct 11, 2001 After viewing dozens of GIA certs. through Blue Nile, I am constantly frustrated that there is no consistent format. What I mean is that on some certs. there are the crown and pavillion angles, etc. and some certs. are totally blank there, with only the clarity diagram at the bottom.I appreciate that AGS gives a detailed diagram, complete with all angles, for every diamond. Any reason why GIA is not consistent? Thanks.
