The Greater Denver Area Gem & Mineral Council hosts the Denver Gem & Mineral Show in conjunction with the Hardrock Summit. The event is held at the Colorado Convention Center.
The Denver Gem & Mineral Show includes club tables, speakers, special exhibits, and dealers selling rocks, minerals, gems, and fossils. If you are interested in dealer space, please email us and the selection committee will send you an application.
The 2025 mineral theme for the Denver Gem and Mineral Show is "Barite and Calcite from Worldwide Localities." These two minerals, often associated together, are found in sedimentary, metamorphic, hydrothermal veins and even rarely igneous pegmatites. Calcite localities in Colorado are also abundant from the hydrothermal veins in the San Juan mountains, and the sedimentary rocks of west slope Colorado and in the septarian nodules in the Great Plains.
About the Denver Gem & Mineral Show
In the 1950s, different gem and mineral clubs and societies put on their own gem and mineral shows, but in the 1960s the Denver Gem & Mineral Show was born when the organizations combined their small shows into one.
The Denver Gem & Mineral Show, which began in 1967, grew into the second-largest show in the United States and attracted the numerous satellite shows that continue today. The show continues to display exhibits from a number of regional and national museums that remain key attractions of the show along with other activities.
The Greater Denver Area Gem & Mineral Council is a non-profit 501(c)(3) corporation organized exclusively for charitable, educational, and scientific purposes.
