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, as well as proportion grading. 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 certificate is most widely accepted as being the most unbiased and accurate grading for a diamond. Typically when a diamond has a GIA certificate, the diamond is worth much more, because any buyer will be assured that the grading is accurate.

The Gemological Institute of America (GIA), is a recognized industry authority for grading diamonds and gemstones.

The Diamond Certificate, issued by the European Gemological Laboratory (EGL), details the same variables that make up the Four Cs as the GIA. The diamond certificate records all the relevant information pertaining to the diamond, including carat weight, color grade, clarity grade, measurements and physical properties as well as plotting diagrams.
