The Princess of Wales made her first public appearance of 2025 at the Royal Marsden Hospital in London, where she was treated for cancer last year.

The impressive ring, which features a 12-carat Ceylon sapphire surrounded by 14 solitaire diamonds set in white gold, made its return after Kate had worn a different eternity band in recent months.

The Princess of Wales was spotted wearing a very special piece of jewellery during her first solo engagement last week.

Princess Diana picked her 12-carat sapphire and diamond engagement ring. Prince William proposed to Kate Middleton with the same ring.
