    The Jackpot of Gems has been held in the Reno area for over 50 years. The show is put on to educate people who have an interest in minerals and gems that are so abundant in our State. RGMS members display over 30 cases of rocks, gems, and minerals. There are demonstrations showing how to make some of the beautiful things shown in the Display Cases. There is a booth high-lighting fluorescent features of some minerals that has been called “nature’s light show”. Expect to learn something new about rocks and minerals in the State of Nevada. It is a fun hobby to learn about and the Show is enjoyable for the entire family.
    There will be raffle tickets available for fabulous prizes. The Wheel of Fortune is a special place for children who spin the wheel to win fun rock and gem specimens. We also have a new Kids Corner with rock painting and a scavenger hunt. There are great bargains available in beads and minerals in the silent auction held every thirty minutes. Come join us!
