⭕ Received these a few years ago as payment from work I did for a client. From the information I have gathered a while back is the gold ones are vintage rolled plated backs made around 1904 and I believe the stone in them maybe moonstone. Information Ive gathered on the other ones are called the knot cufflinks made from sterling silver. Other than the fact that these are genuine Tiffany cufflinks I cannot confirm that the rest of the facts are 100% authentic. I do know the price Im asking is very. Price included with shipping I will accept Western Union or PayPal as payment methods.
