AGTA Member

AGTA members believe in more than just selling the world’s highest quality gemstones and cultured pearls. They share a mine-to-market mentality-the belief that the gem trade should be as transparent and ethical as possible.

That’s why, in 1984, the AGTA and its members developed the industry’s strictest and most comprehensive Code of Ethics and Fair Business Practices. Every year since then, the AGTA and its members annually commit to leading the industry in standards of disclosure, transparency, and ethical practices.

The AGTA and its members take pride in working toward a gem industry that benefits everyone involved. Whether it’s investing in the communities that produce gemstones, supporting individuals whose lives have been impacted by the gem trade, or cooperating with foreign governments to improve working conditions, AGTA members continually work to hold the gem industry to the highest possible business standards.
