The Queen wore the same broach in a televised address today as she did on her honeymoon in a touching tribute to husband Prince Philip.
Her Majesty placed the sapphire chrysanthemum piece on her jacket as he battles illness.
The Queen, who was addressing the nation for Commonwealth Day, was first seen in the broach on her honeymoon in Broadlands, Hampshire.
It is made with sapphires and diamonds set in platinum, The Express reports.
She had also worn the accessory to mark her and Philip's 60th and 73rd wedding anniversaries.
During the appearance the Queen was joined in the address by senior royals including Charles, Kate and William.

Notably absent however was her husband, who has been unwell in hospital since February 16.
The 99-year-old was transferred back to a private hospital after successfully undergoing a procedure to treat a heart condition on Friday.
Buckingham Palace said in a statement: "The Duke is expected to remain in hospital for continuing treatment for a number of days."
The brooch showed how Prince Philip was out of the Queen's sight but not her mind on a day in which Meghan and Harry's interview has dominated the royal spotlight.
The Queen stressed the importance of staying in touch with family and friends during "testing times" in her message this afternoon.
She celebrated collaboration but the message stood in contrast to the troubles facing the royal family.
Focusing on the global impact of the coronavirus pandemic, the monarch spoke of using technology that "transcends boundaries or division" and how there has been a "deeper appreciation" of the need to connect to others during the Covid-19 crisis.
She also praised the "selfless dedication to duty" seen across the Commonwealth, particularly on the front line.
"The testing times experienced by so many have led to a deeper appreciation of the mutual support and spiritual sustenance we enjoy by being connected to others," she said.
Buckingham Palace is bracing itself for what Harry and Meghan will say in their controversial two-hour conversation with Oprah Winfrey - which airs on Sunday in the US, while the Duke of Edinburgh remains unwell in hospital.
