Eagle-eyed royal fans were quick to point out that the former actress was wearing a third ring and that her engagement ring - designed by Prince Harry himself - had undergone a major transformation.

However, Duchess seems to have reset her ring with a much thinner, diamond-studded micro-pave gold band.
Fans also suspect the third ring was a “push present” from the Duke of Sussex.
