Vintage Cats Eye Necklace & Earring Set

Vanilla acrylic cats eye double strand necklace. Jeweled slide clasp at the back. Matching earrings with clip on lever backs. Unclamped and end to end it measures to about 27 inches long. Another selection from the great-great aunts estate. There are no maker marks on it so sadly I can’t say exactly how old it is. My guess is late 60’s to early 70’s
