Calling all mineral enthusiasts and collectors. From April 10 to 12, 2026, a massive trade show dedicated to minerals, crystals, fossils, gems, and more will take over the Charenton venue with a 53rd edition that’s more dazzling than ever, inviting you to discover stones and their mysteries. More than 5,000 visitors are expected at this new edition of the Mineral Expo.
Mineral Expo 2026
Over three days, the Mineral Expo 2026 will welcome more than 200 exhibitors from all over the world (with over 20 countries represented) to showcase their treasures. They will showcase all kinds of stones, including rough stones (minerals and crystals), cut stones (gemstones), and stones set in jewelry, as well as fossils and meteorites.
In a unique 2,000 m² space, the public will discover true treasures on display at the various booths or highlighted during conferences led by experts at the fair. Exciting workshops on gemmology (where you can learn to cut gems or observe them under a microscope), as well as mineralogy, will offer the chance to learn everything about minerals and their properties.
In addition, attendees can enjoy a meal on-site and chat over a drink at the refreshment stand about these mineral wonders.
