Milwaukee Mineral, Fossil, Gem & Jewelry Show

This is billed as America's largest indoor mineral, fossil, gem, and jewelry show, featuring nearly 1,000 booths spread across 206,000 square feet. You'll find vendors selling directly—miners, refiners, designers, gemologists, and more—making it a great place to browse, learn, and shop for rocks, crystals, fossils, and jewelry. If your family has ever been curious about geology or enjoys hunting for unique treasures, this event delivers that experience on a massive scale. It's designed to appeal to all ages and gets kids engaged with nature and science in a hands-on way. The show takes place over four days at the downtown Baird Center, with convenient parking available and plenty of nearby restaurants and museums nearby, so you can easily make a full day of it. Paid parking is $5, and the venue is family-friendly and accessible for an in-person visit. Tickets are available through Eventbrite, with refunds accepted up to one day before the event begins.
