Bold black and white enamel plaques alternate with opaque glass stone. Largest plaque is 7/8". Necklace length is 16 inches. Silver color metal. Previous owner has added a one inch extension that I've left attached. Original closure remains in place and I'm happy to remove the additional length at buyers request. Ca., 1930's and is in very good condition. This is a sweet necklace that wears beautifully!
