I've been told that certs from the various organizations can't be directly compared as some are more critical than others. HRD claims that they are the only which has been able to meet ISO 9000 requirements as the process they follow is the only one which consistently "regrades" diamonds with the same grading.Which certs can be trusted and how can two diamonds with different ones be compared?
