Our Gem Show

The CCM&GS; annual Gem & Mineral Show is the biggest rock and mineral show in the county.

Save the weekend. Come to the Show!

  • Twenty-five Dealers will be showing and selling rocks, minerals, fossils, precious and semi-precious stones, settings, beads, and equipment.
  • Over fifty displays tell the stories of the earth, the minerals and its gems, and the history of our explorations.
  • Highly skilled craftsmen will be demonstrating their techniques in wire wrapping, faceted, cabochons, stone carving, and more.

One of the must see displays is the fluorescent room where hundreds of rocks and minerals glow in the dark and seem to vibrate in space under the activation of ultraviolet light (black light). Kids love it!

Gourmet food and soft drinks are available at the world-famous Diablo Dan Café.

The CCM&GS; Gem & Mineral Show is open to the public. Admittance is reasonably priced, and children under 16 with adult are free. The whole family can have an afternoon of entertainment and fun for $12. That’s less than a movie! Plus, click here to receive a discount voucher to save even more.

Join us the first weekend in November. Doors open at 10:00 am Saturday and Sunday. Closing time is 5:00 pm each day.
