When Meghan Markle stepped out in public with her new re-designed engagement ring after the birth of her son Archie, we weren’t sure why the sudden change had occurred. 

However, according to the book Finding Freedom, it has now been revealed this was all Prince Harry's doing.

It's claimed that the Duke of Sussex had the plain gold band changed to the pave diamond style the royal wears today at the same time he created a bespoke eternity ring for his wife that he gifted her to mark their first wedding anniversary.

“On May 19, 2019, Harry also surprised his wife of one year with the gift of a ring that he had created with jeweller-to-the-stars Lorraine Schwartz, a favourite of Meghan's,” the authors Omid Scobie and Carolyn Durand wrote.

“The conflict-free diamond eternity band paid homage to the family of three with Meghan's, Archie's and Harry's birthstones (peridot, emerald, and sapphire, respectively) on the underside of the ring.”

The jeweller told the authors the “romantic” and “thoughtful” prince “wanted to make it special”.

At the same time as he had the band made, Harry got Schwartz to re-size and reset her engagement ring.

While the reason behind this change has not explicitly stated, it seems that the Duke of Sussex did it so the two rings that sat either side of Meghan’s welsh gold band would match.

The first engagement ring of the former American actress was a plain gold band with three large diamonds.

The largest ring of the trio is the centre stone, which was sourced from Botswana, where the couple shared their first holiday together.

The two smaller stones on either side are from Princess Diana's personal collection.

During their engagement interview with the BBC, Prince Harry revealed more details behind the 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.”
