In recent months, a new ring has also appeared on the Duchess' hand, believed to be a first anniversary present or a gift from Harry for bringing their son into the world.
Prince Harry and Meghan will break away from the Royal Foundation and hope to establish a new charity by the end of the year, according to royal aides.
The ring initially had a gold band, which seems to have been replaced by a delicate diamond band.
Last February, the royals were dubbed the "fab four" by media when they appeared together for their first official engagement - a Royal Foundation forum - and Meghan only became its fourth patron in May a year ago when she married Harry.
The band itself also looks thinner; perhaps it has been shaved down to match sit in better with her eternity ring and Welsh gold wedding band. The two side stones are from the personal jewellery collection of Princess Diana.
Originally, her engagement ring had a band of plain yellow gold.
Donald Trump 'willing' to meet with Iran but offer comes with warning
Iran has decried the US sanctions , which essentially bar Iran from selling its oil internationally, as "economic terrorism ". Trump's tweets add to his record of seeking a wider drawdown of the USA diplomatic and military footprint around the world.
Her original ring was designed by court jewellers Cleave and Company and Prince Harry.
United Kingdom noticed. The new mom chose to replace the thicker gold band for a dainty pavé one, which looks stunning next to the wedding band she received from Harry on their big day.
Levin also said that there's been talk that William had told Harry he was rushing things with Meghan, which Harry "took very badly" - a rumor that's circulated for some time now. They announced their engagement in November 2017 and got married in May 2018.
"Meghan knows if she stays in Britain, this will always mean living in their shadow".
It's likely the engagement ring was redesigned recently, as during the later stages of her pregnancy the Duchess was often seen without her engagement ring, which could have been due to her fingers swelling.
