Vintage 1950s Christian Dior Rhinestone Dual Brooch & Scarf or Dress Clip

Beautiful, rare, vintage 1950s Christian Dior dual brooch and scarf or dress clip. Ruffled filigree or repousse silver-tone metal with blue marquise Austrian rhinestones nestled in the ruffle, and a large lighter blue topaz colored rhinestone centered in between them. Marked with French notation indicating a patent on the clip mechanism; otherwise unsigned. I’ve had the brooch professionally authenticated (and will pass certificate information on to the buyer), as well as consulted on by an independent appraiser (Dr. Lori Verderame). And then, of course, everything $500 or more goes through Poshmark authentication as well. Fabulous piece for a collector.
