This 1920s necklace with red glass in a "step" pattern (also known as "skyscraper") illustrates a popular Art Deco motif. The seven molded, faceted glass panels are prong-set on silver-tone embossed backs. The metal folds over the stone bottoms. Red glass necklaces from this era are hard to find because gold was used in formulating the color. This piece closes with a spring-ring clasp. The delicate link chain adds special appeal. An extender can be added if needed.
