This is a vintage 1960s Monet choker necklace made up of heavy linked gold chain. The clasp is stamped with Monet, which was the stamping used after 1955. The piece measures 16 1/4 long and is in very good condition. Monet is the brand name of the Monocraft Products Co, founded in 1927.
This is a very nice quality choker - Monet used to triple plate their gold plated necklaces - very contemporary looking, easy to wear today!
