Kate Middleton made her second major appearance this weekend following the end of her cancer treatment, maintaining a streak of keeping up royal duties despite health issues.

During her Nov. 9 appearance, Princess Kate paid a subtle tribute to her late mother-in-law, Princess Diana, wearing a pair of Collingwood pearl earrings that once belonged to the former royal, People reports.

“She’s doing well,” William told The Times, referring to his wife and her health. Kate has started to make her slow return to public duties, even attending the National Service of Remembrance ceremony in London on Sunday alongside other senior members of the royal family.
