Mountains of Minerals 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.
