Vintage Miriam Haskell Choker Necklace Double Layer Faux Pearls

Beautiful vintage Miriam Haskell choker with double-layered faux pearl strings and central beaded and floral metal pendant. Stamped Miriam Haskell on clasp interior. 15” across. 14” around inside. Not sure on era, but a piece with a similar clasp is said to be from the 1940s. Another listing estimates it to be from between 1960-1969. If you can date this one, please let me know. In very good vintage condition with something missing from the central pendant -- there are some rings that hang from the bottom of the pendant but nothing that attaches to them. Seems like it might be missing a bead or two on the back clasp too. Some minor tarnish to the back of the metal pendant. Want more info? Pop by my next Posh live show :)
