Irvington Fossils and Fluorescent Minerals highlight Gem and Mineral Show

Submitted By Mike Tice

The Mineral and Gem Society of Castro Valley (MGSCV) will be hosting its annual three-day show and sale on February 21, 22, and 23 at the Newark Pavilion. Anything and everything that has to do with gems and minerals Ð fossils, gemstones, jewelry and more Ð will be displayed for all to admire and purchase. Members will demonstrate a variety of lapidary skills and over 35 members and hobbyists will display everything from carved turquoise to petrified wood.

The Fluorescent Mineral Society will be showcasing rocks and minerals (and a scorpion) that glow under ultraviolet light. Back again this year will be the popular geode splitter, where geodes purchased for a nominal fee are split for you as you watch. The childrens' spinning wheel, a perennial favorite, will also be back.

But the big excitement this year is on view thanks to Dr. Joyce Blueford and the Math Science Nucleus of Fremont. The main stage of the Pavilion will display the Irvington Fossils unearthed by "Boy Paleontologists" who were honored 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 created such an international sensation that a section of geologic time, the ÒIrvingtonian StageÓ within the Pleistocene Era, was named in their honor.

A beautiful 16-carat Australian Opal pendant created by Ed Rigor and valued at $1,200 will be this yearÕs raffle prize, and the popular auction of membersÕ lapidary creations (such as the turquoise tree by Doc Buschke) will be held as a silent auction/raffle throughout the three day event.

For many attendees, many who return year after year, a primary attraction is the incredible array of lapidary and earth science items for sale. Finished jewelry, faceted stones and settings, beads and supplies, cabochons and rough slabs, minerals, fossils, petrified wood, crystals, opals and much more are available. The ever-popular donated book sale is also back.

The Food Truck Mafia will be on site all three days, with a variety of trucks featuring an unique array of gourmet food items.

Established in 1948, the Mineral and Gem Society of Castro Valley has since become one of the most successful non-profit 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 including books, videotapes, DVDs and gem and mineral-related research materials.

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 field trips with their teachers are treated to free tours at the show's Friday, February 21 session. Schools interested in attending this year's show are encouraged to contact for more information.

A three-day pass is $6 at the door. 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 admission coupon, visit
