Mountains of Minerals Show 2021

The Spring in Mariposa is an ideal time to hold the annual Gem and Mineral show. However, we’ve adjusted to ongoing 2021 health requirements, and the new dates for 2021 are October 30th and 31st.

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, speakers give presentations on rock and mineral topics, and demonstrations of lapidary techniques are show highlights.

Hosts of the show:

Many details have now been worked out, and again this year the location is the Mariposa Fair Grounds.  This show is usually the only Gem Show in California at that time.  Mariposa is very near the geographic center of California, convenient to central San Joaquin Valley and Yosemite National Park.

This will be the 20th annual show, which takes place at the Mariposa County Fairgrounds, on historic Highway 49, two miles south of the town of Mariposa, or 30 min. North of Oakhurst. Admission is $3 for adults, 12 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. California State Parks will offer a variety of children’s activities at the show. In addition to viewing the spectacular California State Mineral Collection, kids can go on a scavenger hunt in the museum and explore rocks and mineral crystals at the touch table. All activities and demos are free.

Several guest speakers and demonstrations are on the schedule. In 2019, we had speakers on Saturday at 11:00 and 2:00, and Sunday at 12:00 and 2:00.

Our speakers addressed Toxicity in Rocks and Minerals (“rocks you should not lick”) and California gold, relating to specimens on display or for sale in the museum. This year, on Saturday at 12:00, visit our gold miners camp, where Museum docents will demonstrate gold rush mining methods. See the tools, weapons and methods used by the 49ers to survive and find gold during the gold rush.

The show includes a silent auction of jewelry, rocks, and minerals. Geode cutting is back again by popular demand, 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.

This year’s vendor information letter is available here.  The vendor registration form is a separate document available here.

    1. This evening we learned that our show for 2020 is canceled, due to government health requirements. We will update you for 2021 as we develop plans.
