Antique Art Nouveau 800 Silver Blue Enamel Portrait Brooch Signed European Maker c1900

A rare and beautiful antique brooch from the Art Nouveau period, crafted in 800-grade Continental silver and finished with hand-applied blue enamel. The brooch features a portrait motif — a defining characteristic of the finest European Art Nouveau jewellery from the turn of the 20th century — and bears a signed maker’s mark, significantly elevating its provenance, traceability, and collector value.

About 800 Silver Art Nouveau Portrait Jewellery

800-grade silver — 80% pure silver, the standard hallmark for high-quality Continental European jewellery production — was used extensively by German, Austrian, Italian, and French jewellers during the late 19th and early 20th centuries. It is distinct from British sterling (925) and is a reliable indicator of European origin and period manufacture.

Art Nouveau portrait brooches featuring enamel work — particularly plique-à-jour, champlevé, or painted enamel in blue or green tones — are among the most actively collected categories in antique jewellery. The combination of a signed maker’s mark with portrait imagery and enamel work places this piece in the upper tier of wearable Art Nouveau antiques.
