Love From Our Members

Richard Hughes headshot.

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.

AGA has enabled me to interact with the best minds in our industry. I have forged many new relationships, friendships and broadened my knowledge well beyond what a mere 40 years of experience can bring.

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.
