This past weekend was the locally-famed gem and mineral show at Centennial Hall in Hayward, put on by the Mineral and Gem Society of Castro Valley. All volunteer-run by the members of MGSCV, the show includes faceting and cabbing demonstrations, walls of displays ranging from gemological education to sorting different salts, to examples of rough gem specimens next to cut and finished specimens.And, the most fun? The fluorescent mineral room:
One whole room dedicated to minerals and rocks that glow under short- or longwave UV light. One of the hotspots for collecting is a site in New Jersey. Sign me up.
