Vintage Avon black onyx ring, 1983 'Victorian' faux black onyx and diamond chip, gold tone, rhinestone accent, size 5 1/2 ring. This is a pretty Vintage Avon Ring from the early 1980s. It has an oval Black Onyx with a solitaire rhinestone set in a silver marquee in the middle with accents of gold tone metal over it. Signed Avon and is in very good condition. It will look good every day or for a special occasion. This is in good vintage condition.There is slight scuffing on one corner which I tried to highlight with lighting. See all photos. The top of the ring measures 7/8" (2.2 cm) X 3/8" (1 cm).
