The first Tucson Gem and Mineral Show® was held in 1955 at a local elementary school. Following its immediate success, the show relocated to a Quonset hut at the Tucson Fair Grounds in 1956. As international recognition expanded, the event moved to the Tucson Community Center in 1973 and subsequently to the Tucson Convention Center in 1990, where it continues to operate today.
Today, the Tucson Gem and Mineral Show® stands as one of Arizona’s premier cultural attractions, welcoming over 50,000 visitors annually and featuring more than 2,000 dealers and exhibitors from around the world. The show displays museum-grade mineral specimens, rare fossils, fine jewelry, and lapidary art.
