Inherited from ancestors, so the age and material are unknown. Is it gold? Coral? I don't know. One was removed to make a necklace, so it doesn't have a top. It's old, so there might be markings, but they're worn down and only a gold testing machine can tell. There are rust, scratches, and stains. Please bid only if you understand everything and won't make any claims. It might be a valuable treasure, but I'm selling it for animal welfare, so thank you.
