AGA strives to offer two educational conferences per year. One in Tucson during the Gem and Mineral Show at the beginning of each year and one in Las Vegas during JCK mid-year.

Meet the leaders. Enrich your knowledge of gemology and gem trade issues by exchanging information with a diverse range of professionals. We've met with gemstone treaters, crystal growers, enhancement detection specialists, designer gem cutters, the trade press, gem instrument developers, computer technology specialists, domestic and international traders and the FTC.

AGA Tucson Conference Jan 31, 2024

Register Today for the 2024 AGA Tucson Conference

The annual AGA Tucson Gemological Conference and Gala will be held on Wednesday, January 31, 2024, in Tucson, Arizona, marking the kick-off of AGA's 50th Anniversary celebration!  AGA invites all to attend. Registration options are available to gemology enthusiasts and guests globally.

The two events, hosted by AGA on the same day, offer flexibility for participation. Registration options include attendance at the conference and gala or gala only. Individuals unable to attend in person may benefit from the "recorded conference registration" for on-demand access to the conference education sessions when published by AGA.

Following the conference, the AGA Gala welcomes attendees to enjoy networking and relationship-building at the cocktail reception, followed by dinner, a silent auction, music and dancing, and the recognition of the 2023 AGA Antonio C. Bonanno Award for Excellence in Gemology (recipient to be announced in December).

AGA's 50th Anniversary celebrations will launch in Tucson with distinguished guests sharing memories from five decades at the conference and gala. The year-long commemoration of AGA’s milestone will honor the contributions of individuals who have played a significant role in the Association's development and success.
