What is the American Gem Trade Association (AGTA)?

Definition
The American Gem Trade Association, often shortened to AGTA, is a United States trade body that represents natural coloured gemstone and cultured pearl dealers and works to keep ethical standards high across the industry. It sets a code of conduct for its members, promotes clear disclosure of any gem treatments so buyers know exactly what they are getting, and runs a gemstone testing laboratory. For shoppers, an AGTA connection is a sign a seller has signed up to industry-recognised honesty standards.
Frequently asked questions
- What does the AGTA do?
- It represents coloured gemstone and pearl dealers in the US, sets ethical and disclosure standards for members, runs a testing lab, and educates the trade and public about natural coloured stones.
- Is the AGTA the same as the American Gem Society?
- No, they are different organisations. The AGTA focuses on the coloured gemstone and pearl trade and ethical standards, while the American Gem Society is broader and best known for diamond grading.
- Why does gemstone disclosure matter?
- Many gemstones are treated to improve colour or clarity, which is normal, but you deserve to know. The AGTA requires members to disclose treatments so you can judge a stone's value and care needs accurately.
