PLACE: 3727 E. Blacklidge Drive
TIME:  7:00 p.m. – Tucson, Arizona Time
WHEN: Monday, November 3, 2025
SPEAKERS:  Les Presmyk & Peter Megaw  

LECTURE:  “The Tucson Gem and Mineral Show® -  Focus on Special, Guest and Competitive Exhibits:"  The focus will be on the Tucson Gem and Mineral Show®, starting with the general Tucson Competition available to all collectors from the young to the most advanced of exhibitors. The concept of special trophies started in Tucson, and includes the Bideaux Trophy for the best Arizona specimen; the Lidstrom Trophy for the best single specimen contained within any competitive exhibit; the Yedlin Trophy for the best case of micromounts; the Best of Theme plaques for the various sizes and categories for this Show theme-related species; and, of course, the Desautels Trophy for the best case of minerals.

The Tucson Gem and Mineral Show ® is most renowned for the number and quality of the Special and Guest exhibits that are brought to Tucson each year. Our Show is like a traveling mineral museum that comes to our own backyard. Putting this together each year is a big feat and the responsibility of Peter Megaw who has been the Show Special & Guest Exhibits Chair forever.

We'll also have a chance to talk about the volunteers that help put on the Show, and the volunteer opportunities open to all our club members. 

All TGMS Members and Guests (invite a friend) are welcome to attend.
