Diana's jewels were covered in her divorce agreement. The royal pieces she received from The Queen as wedding gifts were hers to keep for her lifetime, on condition they could never be lent or sold. In the event of her death, the agreement stated the royal jewels would pass to Prince William for his future wife.
All of her other jewels, including the Saudi wedding suite and the Omani sapphires, were her personal property and were left under her Will to William and Harry. The royal pieces were returned to The Queen as she was still living and the jewels belonged to her.
