The Queen paid a visit to the HMS Queen Elizabeth – an aircraft carrier named by the queen — in Portsmouth on Saturday, ahead of its impending global tour.

The queen wore her “Scarab” brooch in yellow gold, carved ruby, and diamond, a special gift from Philip in 1966. She also wore the important jewelry in a portrait commemorating their 70th wedding anniversary in 2017.

During the visit, the monarch walked onboard the ship, one of the two biggest warships ever built by the Royal Navy, and met with commanders from the Royal Navy, Royal Air Force, and Royal Marines in preparation for the ship’s first operational deployment. An extra 250 US Marines will be involved in the mission.

Over 28 weeks, the ship will lead the United Kingdom Carrier Strike Group on a voyage of over 26,000 nautical miles from the Mediterranean to the Philippine Sea.

During her period of Royal Mourning, the Queen celebrated her 95th birthday at Windsor Castle, but she quickly returned to work, attending her first formal engagement with Prince Charles and Camilla, Duchess of Cornwall at the State Opening of Parliament.

“She understands that she has a job to do, and [Philip] would have wanted her to crack on,” a former Palace aide previously told People. “She did do so when he retired from public life.” Another royal insider added, “She will never abdicate because of duty and honor and public service is so deep in her, as it was for him.”

This isn’t the first time the Queen has paid homage to her husband of over seventy years with a sentimental accessory after his death. The monarch donned a black frock, hat, and face mask to his modest burial ceremony at St. George’s Chapel in Windsor Castle in April, embellished with a big diamond and pearl brooch. The Richmond Brooch, one of the biggest in Queen Elizabeth’s collection, was given to her grandmother Queen Mary as a wedding gift in 1893 before being passed down to the monarch in 1953. Queen Mary used the item as a necklace often, while Queen Elizabeth preferred it as a brooch, which she wore rarely throughout her early reign. However, in recent years, the monarch has begun to wear the brooch on several occasions, including Prince Harry’s 2018 wedding to Meghan Markle, which also took place in St. George’s Chapel.

In addition to wearing the brooch to happy events, the Queen has also worn it to sombre events such as the 2014 and 2018 Royal British Legion Festival of Remembrance to remember those who died in a fight.

“As the daughter, wife and mother of naval officers, I recognize the unique demands our nation asks of you and I will always value my special link with HMS Queen Elizabeth, her ship’s company and their families,” the Queen remarked at the time, referring to her husband.

During a tour with her husband in July 2014, the Queen christened the HMS Queen Elizabeth.

She was also there in 2017 to formally commission the aircraft carrier, when she was joined by her daughter Princess Anne, who was dressed in a naval uniform (she holds some honorary positions in the Royal Navy).
