Gorgeous Vintage Designer Faux Opal Gold-Plated Art Noveau Uncas Ring

Faux opal vintage Uncas designer ring. Hallmarked with the Uncas logo and "Gold-plated" inside. Absolutely unique Art Nouveau pattern. Very nice condition, but with some of the gold plating having worn off here and there, especially on the very back of the ring. Estimated late 70's- early 80's vintage.
