EGL Certification

In the American Diamond Market, most diamond grading certificates are from one of three laboratories; the Gemological Institute of America (GIA), the American Gemological Society (AGSL or AGS), or the International Gemological Institute (IGI). Though in 2022, AGSL merged with GIA, and as such, AGS is no longer offering new grading services.

Several other laboratories offer diamond grading, though with less renown in the US. Some examples of other diamond grading certifications that you may see are the Gem Certification & Assurance Lab (GCAL), Hoge Raad voor Diamant (HRD Antwerp), Gemological Science International (GSI), and European Grading Laboratories (EGL), among others.

The History of EGL

Founded in 1974 in Belgium, The European Grading Laboratories (EGL) claims to be the world’s largest independent network of gemological laboratories. European Grading Laboratories (EGL) has created several regionally based networks that can provide their certification. EGL India, EGL South Africa, EGL Platinum (Isreal), EGL Korea, EGL USA, and potentially more.


EGL Color Grading

There are many claims from diamond experts that EGL grades color too generously. Accuracy is vital in diamond grading, and the belief that EGL is grading inaccurately diminishes faith in EGL certifications.

EGL Cut Grading

As noted with diamond color grading, EGL has scored diamond cut too generously. When listing a diamond as an Ideal Cut, the value diminishes if it only rates as Good with GIA. You may pay less for the diamond, but it could be an inferior stone.  

Pay to Play

There is an unfortunate element of pay-to-play occurring with EGL grading. After a diamond is reviewed, the diamond dealers are shown the grade; if they don’t like it, they are not required to pay for the certificate. This practice incentivizes an erroneously high-quality report.

EGL Grading Controversy

Due to the unreliability of the certification process, RapNet (the gold standard in diamond grading) banned diamonds that solely carry an EGL certificate. In addition, the US branch of EGL attempted to get non-US EGL certificates prohibited by the US Bureau of Customs and Border Protection.  

Diamond Shopping with Confidence

Due to the earlier listed issues, we cannot suggest buying diamonds with only EGL certificates. We cannot claim to know if your grading experience would mirror those that proved to be inaccurate. Other labs have proven more consistent, and we encourage you to use a lab you can trust.

Final Thoughts

GIA is another lab that has international locations. However, they all operate under the same business, giving them a consistent lead. GIA, AGS, and IGI are all dependable labs; their certificates carry the weight of their trustworthiness.
