Prince Harry told the BBC at the time of his engagement: “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 engagement ring was altered around the time the couple had been married for a year.

Instead of a plain gold band, Meghan’s engagement ring now features a diamond band.

The birthstones of Meghan, Harry and their son Archie are also thought to feature in the new design.
