Verify a Diamond Grading Report
The AGS Laboratories' Report Verification enables you to check that the information on your diamond grading report matches the information stored in the AGS Laboratories' diamond report database. If you are not sure where these are located, click on the name of your diamond grading report to see a sample: Platinum Diamond Quality® Document, Diamond Quality® Document, Diamond Quality® Certificate, Diamond Quality® Report, Gold Diamond Quality® Report, Diamond Quality® Analysis, and Diamond Consultation™.

Please enter your AGS number and the Carat Weight as shown on your AGS Laboratories' diamond grading report.  Report Verification service is currently available for documents issued after January 1, 2001.   
A PDF version of the Diamond Quality® Document, the Platinum Diamond Quality® Document, and the Gold Diamond Quality® Report is available for documents issued after September 1, 2009, and for all other documents issued after April 1, 2010.
