Vintage signed Monet pearl necklace with gold filigree box clasp classic 50s 60s

Stunning signed Monet hand-knotted pearl necklace in classic collar length. Gorgeous depth and luster in the pearls which are off white with hints of light blush and light champagne. Elegant and intricate box clasp with filigree open work exterior and vented interior. This is high quality mid-century Monet. This set was owned by my great aunt so I believe them to be late 1950s to late 1960s. Approximately 9” drop, please see pictures for details and condition. Excellent vintage find, great for a bride’s “something old.”
