Vintage 1950's Blue Multi Strand Lucite Necklace

Vintage 1950's- early '60's big multi strand lucite necklace. this is a hefty necklace. The SHORTEST strand measures 20" long. The largest center beads measure 1" across. It appears that the fold over clasp part of the necklace was replaced. It is not an exact match to the necklace ends. No big deal. And not bothersome at all as you can se in the last photo. Otherwise in excellent shape.
