Vintage 1950s Christian Dior Austrian Rhinestone Brooch Clip & Earrings Parure

Gorgeous 1950s vintage Christian Dior set of a dual brooch and scarf or dress clip, and the coordinating clip on earrings, in an oxidized silver metal with colorless prong-set Austrian rhinestones. I've had both the earrings and the brooch professionally authenticated (certificate information will be sent to the buyer), and separately consulted on by an appraiser (Dr. Lori Verderame). And then, of course, everything over $500 goes through Poshmark authentication as well. The brooch is marked France just below the trombone clasp, and with a French notation for a patent on the clip mechanism. Otherwise unsigned. The same brooch is in the Metropolitan Museum of Arts collection with aurora borealis rhinestones (its accession number in their collection is 1974.383.72). I also have the same set with the aurora borealis stones like the Mets brooch listed separately. Fabulous set for a collector.
