AGL Diamond Reports

Specifically designed to assist you, the Advanced Gem Laboratory (AGL) diamond report will foster a more informed decision when shopping for a diamond.

Prepared by professionals, an AGL Diamond Report is a certificate you can use to identify your gem at any time, present or future.

Home to the largest gem and jewelry library in the world, the AGL is a place where experts implement the latest optical measuring instruments and sophisticated grading equipment to determine the accurate measurements of diamonds. Prepared by some of the most experienced gemologists and qualified diamond graders from the Gemological Institute of America, AGL certificates are among the most reliable documents in the world.

If you're interested in a diamond that does not have a report, it is advisable to request that your seller obtain one before you purchase the stone. This can be done by either sending the diamond to AGL for appraisal or by making an appointment with the institution, wherein arrangements can be made to have a report prepared on the same day.
