Do All Labs Grade Diamonds The Same Way?
Definitely not. While Blue Nile adheres to GIA standards, diamond grading protocols, systems and nomenclature can vary by organization. Other labs besides the GIA include the American Gem Society (AGS), European Gemological Laboratory (EGL), International Gemological Institute (IGI), and Hoge Raad voor Diamont (HRD).
