This vintage signed Vendome jonquil glass cocktail ring was advertised in their 1969 collection in a full page advertisement in Vogue Magazine that year (See 2nd photo).
This emerald cut, pale yellow glass stone is prong set in gold plate and measures 3/4" of an inch X 1/2" an inch.
The band is adjustable from ring sizes 5-8 US, and the slide band is square-shaped, ensuring the ring to stay in a level position on the top of your finger. This classic ring is stamped Pat. 2,961,855 (for the square band) on the inside of the ring band and hallmarked "Vendome" under the stone setting. It is in excellent condition.
NOTE: These Vendome cocktail rings were advertised in Vogue and Harper's Bazaar Magazines from 1963-1969.
