Antique French Silver Napkin Ring by Alphonse Debain ​General Description ​This is an exquisite French silver napkin ring from the late 19th Century (Belle Époque period). It is designed in the Japonisme style, which was highly influential in French decorative arts between 1880 and 1900. ​Design & Artistry ​Motif: The ring features a fine hand-engraved scene of a dragonfly in flight approaching a flowering rose bush. ​Symbolism: In the Art Nouveau era, the dragonfly symbolized lightness, transformation, and the beauty of nature. ​Technique: Exceptional detail is visible in the dragonfly’s wings and the texture of the rose leaves. It also features an elegant engraved monogram (likely "AM" or "M") in a stylized script. ​Hallmarks & Origin ​The item bears two critical French hallmarks that verify its authenticity and high quality: ​Minerva's Head (1st Standard): Located in an octagonal frame, this indicates 950/1000 silver (95% pure silver). This is a higher grade than standard Sterling silver (92.5%). ​Maker's Mark (Alphonse Debain): A lozenge-shaped stamp with the letters "A" and "D" separated by a Stork (cigogne). ​Maker: Alphonse Debain, a prestigious Parisian silversmith. ​Active: Registered in 1883 at 79 rue de Quincampoix, Paris. ​Reputation: Debain was a world-class silversmith whose works were exhibited at the Paris World Fairs.
