The Cobb County Gem & Mineral Society’s annual Gem, Mineral & Jewelry Show in November on the last weekend before Thanksgiving. The event takes place at the Cobb County Civic Center and features amazing rocks, gemstones, minerals, and fossils from all over the world. In addition, there is a large selection of beautiful beads, jewelry, and jewelry-making supplies.
The three day event is fun and educational for the whole family. One of the most popular events is Geode Cracking. Kids and adults can select from bins of geodes of different sizes and then use a geode cracking tool to break them in half and discover the wonder inside.
In addition to the many fascinating displays by gem club members, there will be demonstrations of gem and mineral polishing, faceting, and free mineral identification classes. There are also inexpensive grab bags for kids, filled with interesting rocks, minerals, and fossils from all over the world. Door prizes are drawn hourly, admission is free, and parking is also free at the Civic Center.
