Springtime in Mariposa is an ideal time to hold the annual Gem and Mineral show. The hills are green, wildflowers are in bloom, and the weather is usually mild. The 2025 dates are April 12 and 13 at the Mariposa County Fairgrounds.
Email the Show Chair at [email protected] for the Vendor Information Letter and Registration Form for the show.
The “Mountains of Minerals” show serves as a focal point to share mineral specimens from world-wide locations. Dealers from far and wide gather to share their knowledge and stock of minerals and demonstrations of lapidary techniques are show highlights.
This show is one of a few Gem Shows in California at that time. Mariposa is very near the geographic center of California, convenient to the central San Joaquin Valley and Yosemite National Park.
This will be the 30th annual show, which takes place at the Mariposa County Fairgrounds, on historic Highway 49, two miles south of the town of Mariposa, or 30 minutes north of Oakhurst. Admission is $5 for adults, 14 and under are free, and parking is free! Show hours are Saturday 10:00 – 5:00 and Sunday 10:00 – 4:00.
A wide variety of gemstone jewelry and rough, breathtaking mineral and rock specimens, fossils, crystals, beads and mineral related crafts of all sorts will be available from our many vendors.
World class gold and rare gemstones are on display in the California State Mining and Mineral Museum, a permanent part of the fairgrounds, open year ’round. Admission to the Museum is $4.
Joy McClure will hold demonstrations on casting (outside in the Gazebo, weather permitting) both days of the show.

The show includes a silent auction of jewelry, rocks, and minerals. Geode cutting is back again by popular demand. There’s a large raffle, and you will find many unique jewelry items handcrafted by local member artists, at the Mariposa Gem and Mineral Club booth. Local vendors will also be available with a variety of food items.
