Gem show features Irvington Fossils

Submitted By Mike Tice

The Mineral and Gem Society of Castro Valley (MGSCV) will be hosting its annual three-day show and sale on March 1, 2 and 3 at Newark Pavilion. Anything and everything that has to do with rocks - fossils, gemstones, jewelry, and more - will be displayed for all to admire and purchase.

Highlights of the event include a geode splitter, demonstrations of lapidary skills by club members, over 25 display cases containing everything from carved turquoise to petrified wood, and the children's spinning wheel. The Fluorescent Mineral Society will showcase rocks (and a scorpion) that glow under ultraviolet light.

A beautiful opal pendant created by Ed Rigor and valued at $2,200 will be this year's raffle prize, and the popular auction of members' lapidary creations (such as the turquoise tree by Doc Buschke) will be held as a silent auction/raffle over all three days.

A big attraction this year, thanks to Dr. Joyce Blueford and the Math Science Nucleus of Fremont, is a display of the famous Irvington Fossils on the main stage. Local "Boy Paleontologists" were featured throughout the United States in the 1940s. This band of boys, ranging in age from seven to thirteen, unearthed one of the best preserved fossil sites in North America. Fossils from the Irvington District were an international sensation and, in their honor, a section of geologic time was named the Irvingtonian Stage within the Pleistocene Era.

For many attendees, most of whom return year after year, the main attraction is an opportunity to visit 38 dealers selling an incredible array of lapidary and earth science items. Finished jewelry, faceted stones and settings, beads and supplies, cabochons and rough slabs, minerals, fossils, petrified wood, crystals, opals and much more will be on sale. The ever popular donated book sale is also back.

In addition to the club sponsored snack bar, the Food Truck Mafia will be on site Saturday and Sunday, with five trucks featuring a variety of unique and gourmet food items.

Established in 1948, the Mineral and Gem Society of Castro Valley has since become one of the most successful nonprofit organizations of its kind in northern California. MGSCV runs a well-equipped lapidary shop in Hayward where it holds educational workshops on lapidary techniques and jewelry arts for members of all ages and walks of life. In addition, club members have access to a library containing resources such as books, videotapes, and DVDs that illustrate lapidary techniques and give access to gem and mineral-related research.

As a non-profit educational corporation, MGSCV and its 171 members are active participants in the community and local schools, helping to increase the knowledge and understanding of the sciences pertaining to minerals, gems, fossils, geology, and related subject matter. Year-round MGSCV club members volunteer in schools to teach children about geology and rocks. Classes on a field trip with their teachers are treated to free tours at the show's Friday session (March 1). Schools interested in attending this year's show are encouraged to contact for more information.

Adult tickets are $6 at the door and children under 13 are free with adult admission. For more information about the show, the Mineral and Gem Society of Castro Valley, or to get a $1 off coupon, visit
