Diamond Certificate Verification Check by Laboratory

The most recognized diamond grading laboratories include GIA, IGI, AGS and EGL. These laboratories offer an online verification check on the reports that have been carried out by the gemologist within the institute. The verification check shows that the report or certificate is authentic and matches the diamond.

Find the corresponding institute that has given the report and enter the report number and the carat weight of the particular stone.
