After proposing to Diana at a private dinner at Buckingham Palace, Charles gave the late Princess of Wales the change to choose her own engagement ring from the crown jeweller at the time, Garrard.

In the end, Diana chose an oval sapphire surrounded by 14 diamonds, set in 18-carat white gold.

Following her tragic death in 1997, Diana's jewellery was left to her two sons, William and Harry, who reportedly chose a number of pieces themselves.

It has been reported that it was actually Harry who chose to keep the sapphire engagement ring, but willingly offered it to William and Kate when they got engaged in 2010.
