About the Accredited Gemologists Association

Established in 1974 by Antonio "Tony" Bonanno (as alumnae of the Gemmological Association of Great Britain), AGA was envisioned as a network for sharing gemological information and skills. Graduate gemologists of the Gemological Institute of America joined in 1975. The international Accredited Gemologists Association of today proudly counts among our members some of the worlds leading independent gemologists.
