Overview
- Sotheby’s announced the consignment on Thursday, September 10, 2026, and plans to sell the black silk Christina Stambolian gown in New York on December 9 during its Luxury Week.
- The auction estimate is $150,000–$300,000 and the lot will include a rare 1997 catalogue numbered and signed by Princess Diana and Christina Stambolian.
- Before the sale the dress will be publicly exhibited at Sotheby’s London from September 18 to 24 and will then travel to shows in Hong Kong and Geneva ahead of the New York viewing.
- The gown was first sold by Diana in June 1997 to raise funds for cancer and AIDS charities, has been in private hands since, and the current consignor remains anonymous.
- Sotheby’s frames the sale as both a cultural moment and a charitable gesture, a move that could renew market interest in Diana memorabilia and raise funds for NHS Lothian Charity on behalf of the Royal Edinburgh Hospital.
