Vintage Tiffany & Co 18K yellow gold on sterling silver. The entire Piece is sterling with 18k overlay on the chain and the top layer of the pendant as confirmed by a local jeweler. Some of the plating has come off of the chain. Necklace and Pendant is a souvenir from Crystal Symphony world cruise 1998. Back of pendant is signed Tiffany & Co. 18k on sterling. Chain has a tag that says 925 on one side and Tiffany & Co. On the other. Comes with the original famous blue Tiffany & co. Bag. Could use a good buffing but I’ll leave that to the new owner.
