Tucson is known in the gem and mineral world for its incredible 40+ shows in February, but the town also hosts a few great gem and jewelry shows in September, at which over 200 vendors come in from all over the world to sell. Three of the same show promoters who set up in February in Tucson open shop in September as well, at the same locations as their February shows. Gem & Lapidary Wholesalers (G&LW) holds its Holidome Show, the J.O.G.S. (which, by the way, stands for Jewelry and Organic Gems Show) folks open the door at the Tucson Expo Center, and the Best Bead Show sets up at the Kino Community Center. Buyers who have exhausted most of their February Tucson supply come to Tucson in September to stock up through the end of the year and in to January ... until they come back to Tucson again in February. Be prepared for temperatures in the 90s and even over 100, as early September is still summertime in this arid Sonaran Desert region of Arizona.
