The Spring in Mariposa is an ideal time to hold the annual Gem and Mineral show. The dates for 2018 are April 7th and 8th.
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.
