When it comes to minerals and gems, California’s big. There are over 30 festivals, fairs, shows and expos in 2014 featuring gemstones, stones & minerals, rocks, jewelry, beads, rings, necklaces, spheres, sculptures and more. The beauty of these events is that they’re often free or fairly cheap to attend, and you can just look, or buy great products with access to many jewelers and lapidaries in one location.
