There are various gem laboratories out there providing their own independent judgments on diamond specifications. Unfortunately, often these laboratories vary in their strictness in grading of the diamonds. Here we list only the most respected and well known laboratories:

GIA - Gemological Institute of America:

GIA Lab sets the standard for diamond grading and is by far the most commonly used and respected lab in the trade.

The Diamond Dossier®, is GIA report issued for diamonds weighing less than 1 carat.

EGL - European Gemological Laboratory:

EGL certificates are the second most common certificates on the market. EGL Lab tends to be more lenient in their color, clarity and cut grades than some of the other labs.

AGS - American Gem Society

The AGS certification is in par with GIA in being very strict in their grading and this laboratory is generally used for very well cut to ideal cut stones only.

IGI - International Gemological Institute
