The markings I can't see because my glasses are broke and it's an 50 year old chain and I don't think the diamonds are real but they might be I'm not sure but I do know that the piece the diamonds are in is not real
Ur welcome and sorry if my glasses wasn't broken I would look for the markings if they are still there since its 50 years old but the chain is in great condition to be that old and alrighty and thank you and you have a great afternoon as well
My mother in law gave this to me and she said her mother gave it to her 50 years ago and her mother told her it was real gold plus if it was fake the chain would have faded after all the years and my mother in law added the pendant
