Unusually decorated with small partridge feathers like the yellow-gold gilt necklace commissioned by Elsa Schiaparelli (1890-1973) that is featured on the front-and-back covers and centerfold of the French costume-jewelry hardcover book, Lina Baretti Parures, authored by Patrick Mauries, this unique pave-crystal yellow-gold gilt metal partridge-on-a-branch brooch is further distinguished as an unsigned Parisian-couture piece for Italian-born Schiaparelli with its combination of embossed text "Made In France" and "Modele Depose", along with the trombone clasp often used in the early 20th Century for custom-made French small brooches. The book centerfold on pages 90-91 shows a closeup of the feathered necklace created by French-born Corsican Baretti, whose intricate decoration often mixed ready-made textural or shiny materials like velvet, cork, wire, rhodoid, raffia or feathers with custom-made metal, plastic or glass by specialized Parisian workshops such as Maison Gripoix. The Baretti-book caption about the attributed necklace notes: "Collier realise pour Elsa Schiaparelli. Liege, soie, cannetille, perles de verre et plumes de perdix. Chaine en metal." While none of the captions date this necklace--which could have been from the same commission as our brooch--Baretti created one-of-a-kind jewelry for Schiaparelli from the 1930s to the early 1950s until the fashion designer retired. Our brooch was most likely made for a fashion-show debut of one of Schiaparelli's themed clothing collections in the late 1930s for which she commissioned many costume-jewelry paruriers including Baretti.
