This Choker Necklace and bracelet set is a replica of that worn by Jackie Kennedy. They each come with their original boxes of blue velvet, certificates of authenticity, even the foam protectors and original cardboard coverings for the boxes. They have never been worn and only removed for measuring and photo purposes. The choker is 15 totally extended, but the curvature is not included with that measurement. The bracelet is 7″ plus a 1″ easily attached or removed with a fold over clasp.
