Member Testimonials
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.
AGA strongly emphasizes the value of continuing education and professional networking. The opportunity to learn from the leading names in gemology at AGA events and exchange experiences with colleagues are my favorite benefits of being a member.
The one event of the year that I look forward to attending is the AGA’s Tucson conference. Nowhere else can I pack as much learning into a single day. And it is not just the lectures, but practical sessions that help me grow as a gemologist.
