Meghan Markle's engagement ring

The 'Suits' actress showed off her stunning three-stone band when she and her new fiance Prince Harry posed for pictures at the White Garden - a memorial spot for the royal's late mother - in the grounds of Kensington Palace on Monday (27.11.17) afternoon, a few hours after it was announced they are to marry next spring.

Harry, 33, designed the ring himself and it features a gold band bearing two diamonds taken from his beloved mother's personal collection either side of a larger central stone from Botswana, which is where the couple enjoyed a safari holiday in September.

The ring was made by Cleave and Company, Court Jewellers and Medallists to Her Majesty The Queen.

A newly engaged Prince Harry couldn't hide his grins as he posed up with his new fiancée Megan Markle, who gave us a glimpse of her stunning three stone diamond engagement ring - with two stones from Diana's personal collection - for the first time after her love's secret proposal.

The sunken garden where the couple posed for pictures holds special significance for Harry as it was renamed the White Garden earlier this year to honour his beloved mother on the anniversary of her death in a Paris car accident.

The White Garden was planted at the Palace, Diana's former home, and Harry and his brother Prince William planted white roses in tribute to their parent.

The photocall comes a few hours before Harry and Meghan - who have been together for 16 months - will sit down for their first interview together, with the chat airing on TV on Monday evening.
