Antique, Victorian style, Shell Cameo, Brooch/Pendant, Silver

A simply beautiful cameo of a demure lady wearing her hair up with light curls. There are no identifying marks as to if it's pure silver but the appearance, tarnish and lightness feels like silver. The green patina observed is likely from copper content in parts of the sliver detail. No discerning Hallmarks. It's a lovely and romantic piece. Measurements 1" X 1 1/4"
