Pocatello, ID

The Crystal Festival gem and mineral show comes to Pocatello, Idaho — the Gateway to the Northwest and one of the most geologically diverse regions in the American West — for a fall weekend of rocks, minerals, gems, and crystals. If you've been searching for a gem show in Idaho, a rock and mineral show near Pocatello, a gem fair in Idaho, or a crystal show in southeastern Idaho, the Crystal Festival Pocatello is the event you've been waiting for. Pocatello sits at the crossroads of the Snake River Plain and the Portneuf Range, in a region shaped by volcanic activity, ancient lake beds, and the same geological forces that created Idaho's legendary gem deposits. Idaho is the Gem State for good reason: it's home to the world's only commercial source of star garnets, stunning opals from Spencer, the famous Hells Canyon agates, and significant deposits of jasper, obsidian, and petrified wood. This Crystal Festival show brings 30+ curated vendors to Bannock County, offering collectors and enthusiasts from Pocatello, Idaho Falls, Twin Falls, and the greater southeastern Idaho region access to a world-class gem and mineral marketplace. Browse Idaho star garnets, opals, agates, fossils, crystals, and specimens from around the globe. Kid's activities at every show. Free admission and free parking.
