What is the difference between the grading reports issued by the GIA and the EGL?
The GIA Diamond Grading Report and Diamond Dossier detail all the individual characteristics of the diamond commonly known as the Four Cs. The Diamond Grading Report includes a diagram of the diamond indicating the type, size and location of distinguishing marks that determine its clarity grade. The Diamond Dossier, which is issued for diamonds weighing under 1 carat, does not include a diagram, but does include a laser inscription registry, which notes the unique GIA report number that has been laser inscribed onto the diamond. THE GIA The Gemological Institute of America founded by Robert M. Shipley, is a recognized industry authority for grading diamonds and gemstones. In 1953, Richard T. Liddicoat created and introduced the international Diamond Grading system. Primarily an independent nonprofit organization GIA is well known as an authority in gemology.
