However, soon after the wedding, the Princess had the sapphire brooch converted into the clasp for a magnificent seven-strand pearl choker.[30] One of the earliest famous appearances was in 1985, when she wore the choker to dance with John Travolta at the White House.[2] A favourite piece of jewellery, the Princess wore this seven-strand pearl and sapphire choker for occasions at home and abroad. Another famous appearance of the sapphire choker was in 1994, when the Princess wore the piece (with the daring 'revenge' dress) on the night the Prince of Wales confessed to adultery with Camilla Parker Bowles.[3]
