The 57-year-old royal was accompanied by her husband Prince Edward as she made her grand entrance at the celebratory event, where South African President Cyril Ramaphosa is being fêted during his two-day state visit by the new monarch King Charles and his wife Queen Consort Camilla.

But it was Countess Sophie's glittering tiara that really caught our attention. The beautiful piece, which she debuted in 2005 during Prince Albert II of Monaco's enthronement celebrations, comes from her personal collection and is one of her go-to choices for similar state events.
