This is a great Art Nuevo style vintage cocktail ring. It is made by Art, which was also known as Mode Art, most likely in the late 1950s. The goldtone ring has an adjustable band. The ring has one large emerald green cabochon in the center and is surrounded by emerald and clear rhinestones. The ring is in good condition, but does show some signs of age and wear. The ring is signed ART. It measures 1.5 x 1 inch.
