The American Gem Society (AGS) and GIA (Gemological Institute of America) have advanced our long-standing collaboration in pursuit of innovation, serving today’s jewelry professionals and our shared consumer protection missions. GIA has created an endowment to support AGS and our membership through educational initiatives. The strategic collaboration supports additional member educational opportunities.
As part of this next chapter, AGS and GIA have combined 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 has closed AGS Laboratories. 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.
