American Gem Society

AGS Laboratories Resource Page

The American Gem Society (AGS) and GIA (Gemological Institute of America) will advance our long-standing collaboration in pursuit of innovation, serving today’s jewelry professionals and our shared consumer protection missions. GIA will create an endowment to support AGS and our membership through educational initiatives. The strategic collaboration will  support additional member educational opportunities.

As part of this next chapter, AGS and GIA will combine our gemological research efforts, integrating AGS Laboratories’ unique expertise, intellectual property, and technology to develop new GIA products and services to protect consumers and support the trade. The American Gem Society will be closing AGS Laboratories at the end of the year. This strategic decision allows the Society to focus solely on advancing our mission, education, and membership programs and allows the combined AGS and GIA teams to focus on new products and services.

To ensure your diamond grading needs are met before AGS Laboratories closes at the end of 2022, please review the following Client Checklist and FAQ.
