Overview
A striking example of early 20th-century costume jewelry featuring three emerald-cut cobalt blue glass stones set in a delicate foliate-link chain. The design utilizes stylized leaf motifs and a central drop, characteristic of the transition between the organic Art Nouveau and the more structured Edwardian styles.
Story
Jewelry like this allowed middle-class women to embrace the 'high fashion' of the Belle Époque. Cobalt blue was a favorite for evening wear, designed to glow under the newly popular electric lights of grand ballrooms.
Maker / Origin
While unsigned, this piece reflects the output of major jewelry hubs like Pforzheim, Germany, or Gablonz, where artisans specialized in high-quality 'paste' jewelry. These workshops were masters at making glass look like precious sapphires and silver-toned alloys mimic platinum.
Condition & Value
The necklace appears well-preserved with a lovely aged patina on the metal. No visible chips to the cobalt glass stones are apparent in the photo. The original spring ring clasp appears functional. Excellent condition for its age. Value is driven by the vibrant cobalt color and the intact foliate links.
