As an appraiser, I place a high value on my AGA membership. I have gained practical knowledge from every AGA conference I’ve attended. The networking opportunities are unrivaled. AGA is the only place I know where many of the brightest minds in the gemological community meet to share discoveries, ideas, and theories, having left all egos at the door.
