Our mission is to leave no doubt
about the true value of your diamond
A Diamond Certificate is official documentation of your gem’s quality and main attributes: its Color, Clarity, Cut and Carat weight, which are known in the diamond industry as the 4 Cs.
Diamond and diamond jewelry appraisals are based on grading report results, the approximate market value and the replacement value in the event of theft or loss.
EGL Laboratories now prints its QR code on its diamond reports, becoming the world's first diamond grading institute to issue certificates with its company QR code.
