In pictures: Meghan Markle's engagement ring features some of Diana's diamonds

Prince Harry proposed to Meghan Markle with a three-stone diamond engagement ring that he designed himself. The prince paid a touching tribute to his late mother as the ring features two diamonds from the collection of Princess Diana, who died in 1997 when Harry was 12.

The other stone is from Botswana, a country that is close to his heart. It's also a country the two lovebirds visited this summer to celebrate the 'Suits' star's 36th birthday. The couple debuted the ring on Monday in Kensington Palace's Sunken Garden, where Meghan and Harry posed for official photos.
