These beautiful natural geode earrings are made from genuine agate geodes, which are cut in half to create this look. Each earring is unique as they are natural, but they are cut from the same geode so they match as closely as possible. They are sisters, not twins!! Each piece will vary slightly in shape, color, and size but they are all absolutely stunning! They are approximetly 12mm in size and plated with gold on the edges and back.
