A lot of The Princess of Wales' jewellery collection has remained with her boys, apart from the pieces she loaned from The Queen or the pieces that were sold at auction.
She wrote in a special letter: "I would like you to allocate all my jewellery to the share to be held by my sons, so that their wives may, in due course, have it or use it."
3. Diana's engagement ring was picked out by Prince Harry as a keepsake after her death, but he kindly gave it to William since he got engaged first.
5. The pearl bracelet designed by Nigel Milne that Diana wore with her famous 'Elvis' outfit is now in Kate's collection.
