This necklace is so beautiful. I have been in a Downton Abbey haze all weekend, and I can totally see the Dowager Countess passing this beauty down to Mary or Sybil (never Edith) one night after a spirited dinner where the new footman made a scene and someone fainted.
Detail of English Victorian Wing Necklace. This section removes from the rest of the necklace and converts to an brooch with a clever mechanism that hooks onto the back. All totally original, and probably not out of its box more than a couple times in the last 130 years.
