Vintage 1930's Art Deco Genuine Shell Cameo, Gold Filled Etched Locket, Excellent Condition

Lovely Art Deco ornate locket measuring 1 1/4" l. ( + 1/4" attached "ring" ) x 1" w., ca. 1930's. The rectangular shaped locket was designed with a fancy, four - sided raised border frame, an ornate dark, etched zig-zag pattern surrounding a delicate oval shell carved cameo, and an etched "striped" back. The piece is 1/20 12kt. gold-filled, and although it is unmarked, the locket was tested by a jeweler for gold content. Closing is secure. No marks or scratches that I can see. Makes a cherished & memorable gift !
