Good used condition Tiffany & Co sterling silver knot earrings. As pictured, a few coils have become a bit loosened over time. This does not affect the function/structure of the earrings. It’s not very noticeable either. The earrings are still strong - it’s a cosmetic flaw now if anything. I’ve polished and sanitized both studs. I don’t have the original backs but I’ve purchased brand new sterling silver back that are snug and tight on both posts, to protect from losing the jewelry.
