Tiffany & Co. Tiffany Notes Round Pendant Sterling Silver small box dust bag

Authentic Tiffany & co discontinued notes pendant, not on original Tiffany chain. Box and dust bag and copy of original receipt. Could use a cleaning from Tiffany’s. As stated- chain is not original from Tiffany’s, I’m allergic to the small amount of nickel in silver and replaced all of them at one point to hypo, the current is stamped silver but I do not remember its origin. Can replace with one from Tiffany’s if desired. Questions? Leave a comment below!
