31st Annual Mariposa Gem & Mineral Show

Saturday, April 11th & Sunday, April 12th

10:00 AM to 5:00 PM at the Mariposa County Fairgrounds

Rock lovers, this one’s for you! Explore sparkling minerals and gems from around the world, meet friendly dealers, and catch live lapidary demos that turn rough rocks into dazzling art.

This year’s show features a silent auction of jewelry, rocks, and minerals, plus the return of geode cutting—back by popular demand! Try your luck in the big raffle, and grab a bite from local food vendors while you explore.

Held in Mariposa, you’ll find gemstone jewelry, fossils, crystals, beads, and a variety of rockin' crafts.

Don’t miss the California State Mining & Mineral Museum on-site, home to world-class gold and rare gems—open year-round!

Come for the rocks, stay for the fun!

Admission is $5 for adults, 14 and under are free
