AGTA’s Legacy of Ethical Excellence

In this first half of a two-part series, we explore some of the American Gem Trade Association’s key achievements.


Founded in 1981, the American Gem Trade Association (AGTA) stands as an indomitable pillar of ethical conduct and industry transformation in the realm of colored gemstones. For over four decades, AGTA’s relentless pursuit of uncompromising standards has woven ethics into the very fabric of its existence. This refined commitment to ethical conduct has perpetually shaped the gemstone industry, elevating its practices and safeguarding the interests of consumers.

AGTA’s prestigious gem show in Tucson has remained an influential platform for spreading knowledge and insight since its inauguration in 1982. The show has not merely refreshed the perspectives of jewelers and traders, but has disseminated information concerning gemstone treatments, polishing techniques, inherent issues, and import/export regulations. It is this dedication to enlightenment that has earned AGTA the endorsement of the esteemed Arizona Jewelers Association.

AGTA dealers, functioning as the gatekeepers of the gemstone industry, filter gemstone treatments before they reach the broader market. They also serve as the vanguards in introducing novel products to gem laboratories for analysis. Consequently, they are the first to explore and engage with groundbreaking gem materials from across the globe, often preceding even the most well-regarded laboratories.
