EGL - THE EUROPEAN GEMOLOGICAL LABORATORY

The European Gemological Laboratory or EGL, was founded in Europe in 1974. A globally trusted organisation, the EGL has offices all over the world, and is committed to honest and reliable analysis results. They are known for having developed grading techniques for diamonds weighing less than one carat, and for introducing the SI3 clarity rating for diamonds.

When various laboratory-created diamonds starting entering the market, the EGL pioneered lab-grown diamond identification. It was the first to alert the public that chemical vapour deposition lab-grown diamonds and high pressure high temperature (HPHT) treated and coloured diamonds were being sold. The EGL is committed to research, and advancing the knowledge we have on diamonds and gems.

Similar to the GIA, the EGL’s grading certificate gives a comprehensive list of a gem’s characteristics. It covers the 4Cs, fluorescence, measurements and proportions, as well as symmetry and cut on most diamonds graded.
