NEW YORK, NY.- Guernsey’s Auction House has announced the historic addition of the magnificent Swan Lake Suite, including a diamond necklace worn by Princess Diana on her last official engagement. Formally known as the ‘Diana, Princess of Wales Swan Lake Suite,’ the stunning diamond and pearl necklace is the only known piece of jewelry worn by Diana that is ever likely to be available for sale.

The necklace is composed of 214 diamonds and seven South Sea pearls, all set in platinum, designed with input from Princess Diana, by the distinguished English firm, Garrard, the Crown Jewelers. Princess Diana wore the necklace June 3, 1997 to the Royal Albert Hall ballet. Following the ballet, she returned jewels to Garrard so earrings could be made to complement the necklace. The earrings were completed during the summer of 1997, only shortly before her tragic death.

Princess Diana’s Swan Lake Suite will be among other rare and meaningful items featured in the Iconic Objects auction, presented by Guernsey’s September 24th at New York ’s Park Avenue Armory. The auction includes items from such extraordinary individuals as John F. Kennedy, Albert Einstein, Frank Sinatra, Harry James, Charlie Parker, Mickey Mantle, Elvis Presley, Marilyn Monroe, Babe Ruth, John Lennon, Michael Jackson, the Duke and Duchess of Windsor, and the Boston Red Sox.
