This is Tucson’s most-attended gem show. We are open to the public and no registration is required. We feature convenient on-site parking and free admission. The 22nd Street Show is notable for its hardwall tents that stretch along I-10 near downtown. In the Main Tent you’ll find an appealing balance of minerals, gems, fossils, dinosaurs, meteorites, jewelry, beads, and art. To its south near 22nd Street, the smaller SHOWCASE tent is a finer experience with wall-to-wall carpeting, full climate-control, larger booths, high-end stage lighting, and 10′ high art walls. The SHOWCASE is a space with heightened elegance in a less-rushed environment that is ideal for mineral, gem, jewelry and fossil dealers who offer better material than in the Main Tent.
