Meghan Markle has been spotted sporting a gift reportedly from King Charles III.

On Monday, Markle, 42, stepped out in Santa Barbara, California, wearing a casual outfit -- a pair of black leggings, a black sweater, a green cap, and white sneakers.

But a piece of jewelry caught the public's attention: the diamond tennis bracelet adorning her wrist.

This marked the Duchess of Sussex's first public appearance since the Dutch version of Omid Scobie's contentious royal book, "Endgame," allegedly named King Charles and Kate Middleton as the royal members who made racially charged remarks about Markle and Prince Harry's son, Prince Archie, prior to his birth. 

The diamond bracelet was reportedly a gift from Charles to Markle before her wedding with Prince Harry in May 2018, according to People and the Daily Mail.

The former "Suits" star was first seen wearing the accessory when she arrived at the Cliveden House Hotel the night before the nuptials.

A few days after the wedding, she was seen wearing it again at a royal garden party, her first royal engagement alongside Charles and the then-Duchess of Cornwall, Camilla.

In 2018, during her and Harry's first major royal tour, the Duchess of Sussex wore the accessory once more, specifically during a stop in Fiji.

The last time Markle sported the bracelet before her recent sighting was last year in November at the 2022 Invictus Games.

The Diamond Line Bracelet from royal warrant holders Bentley and Skinner, as identified by Page Six, features 60 round brilliant-cut diamonds, collectively weighing 2.6 carats.

As of writing, Markle and Prince Harry have remained silent regarding the latest royal family drama, with Middleton and Charles also refraining from making any comments.

Meanwhile, both Scobie and the publishers of his book have strongly maintained that it was a translation mistake, with the author stating in his "This Morning" interview that he never submitted a book explicitly naming Charles and Middleton.

"I wrote and edited the English version of the book with one publisher, [which] then [got] licensed to other publishers." Scobie told the hosts of "This Morning." "I obviously can't speak Italian, German, French, Dutch or any of the other languages that come out."

"I had never submitted a book that had their names in it, so I can only talk about my version," Scobie insisted. "I'm obviously frustrated."
