The Duchess of Sussex's engagement ring appears to have had an upgrade...

Eagle-eyed royal fans spotted the change in the most recent photos of Meghan, from when she introduced baby Archie to the world and her appearance at Trooping The Colour a few weeks ago.

When the couple announced their engagement, Harry explained the sweet meaning behind the design of her ring.

"The ring is obviously yellow gold because that's [Meghan's] favourite and the main stone itself I sourced from Botswana and the little diamonds either side are from my mother's jewellery collection, to make sure that she's with us on this crazy journey together."

The duchess was seen without her engagement ring on a few occasions before the birth of her son. Many thought this had to do with her pregnancy and her fingers swelling, but as she was still wearing her wedding ring, it's possible that this was when the diamonds were being added to the design.

At the Trooping The Colour parade, Meghan also debuted another beautiful ring, which many have speculated could be an eternity ring given to her by Harry.
