The European Gemological Laboratory, or EGL, was founded in Belgium more than 30 years ago. EGL is committed to protecting the integrity of the jewelry trade and promoting public interest through applied science, innovation, education, and exceptional service. The laboratory is credited with introducing new approaches to diamond grading and conducting advanced research with physicists, geologists, and mineralogists.
The EGL is accredited with introducing new approaches to diamond grading, the practice of certifying diamonds measuring less than one carat, and establishing the 'SI3' designation for diamond clarity. An EGL certificate is a valued document that aids consumers in the diamond buying process and is the result of thorough scrutiny of a diamond.
