Gold filled. Vintage. I’m not sure of the age. It appears to have normal, minor wear due to age or being moved around. I don’t see anything else wrong with it. I do not test anything. I only go by what I see and what it says. It is signed. Needs to be cleaned. I haven’t even wiped it off. Not sure what the stone is. Please see photos as they are part of the description. Ships as soon as payment is received. All offers welcome! Thanks for looking!
