The 63-year-old British travel writer and conservationist fell shortly after leaving an after party for the Sotheby's Fabergé Big Egg Hunt at the Paramount Hotel late last night.
Clarence House released the following statement on behalf of Prince Charles and his wife:
"It is with deep sadness that we have to confirm that The Duchess of Cornwall's brother, Mark Shand, has today passed away in New York. Mr. Shand died in hospital as a result of a serious head injury which he sustained during a fall last night."
It continued, "The Duchess, The Prince of Wales and all her family members are utterly devastated by this sudden and tragic loss. Mark Shand was a man of extraordinary vitality, a tireless campaigner and conservationist whose incredible work through The Elephant Family and beyond remained his focus right up until his death."
The Sotheby's charity auction was also attended by Diane von Furstenberg, Princess Eugenie and Princess Ira Von Furstenberg.
Shand had commissioned a painting for the event, which was created by The Prince's Drawing School and signed by the Prince of Wales and Duchess of Cornwall.
The piece was called, "The Royal Egg—Humpty Dumpty, 2014."
