Vintage MCM Lucite beaded necklace with fancy clasp

White & translucent marbled lucite beaded necklace with faceted aurora borealis beads and embellished pretty beaded clasp. It looks great, for being at least 40 year old plastic. One strand on the necklace has been restrung using strong, clear line; the other strand is on its original string that appears to be a cotton/nylon thread that'll need to be replaced in the near future. Diameter is around 25".
