Vintage Avon Necklace 1960’s*

Vintage Avon SP made up of carved blue cabochons, smooth aqua cabochons, and smooth opal like cabachons. I believe it should be from 1960’s. The necklace is on a chain with metal spacers between each jewelry piece. Extremely unusual and definitely vintage in appearance and sure to get lots of compliments! I’ve owned for over 25 years and never worn!
