Britain’s Queen Camilla joined King Charles III for the royal couple’s tour of Canada on Tuesday in the country’s capital of Ottawa. The reigning monarch provided remarks to the first session of the 45th Parliament of Canada.

For the occasion, Queen Camilla wore a navy blue ensemble, featuring a midi dress with rounded shoulders and long sleeves. The queen consort added a coordinated hat to her ensemble with an exaggerated brim and appliqué at the side.

As for her accessories, Queen Camilla styled her three-strand pearl necklace with a diamond clasp at the center and the Queen’s Own Rifles of Canada brooch, which holds a significant symbolic meaning, per Steven Stone jewelry expert Maxwell Stone.

“The Queen’s Own Rifles of Canada brooch is a meaningful and distinguished piece of royal jewelery, symbolizing her deep and enduring association with the regiment,” Stone said in a statement to WWD, via email.

It is The King's 20th and Queen's 5th tour of Canada, with their previous visit being in 2022. Britain's King Charles III is heading to Canada for a brief but "impactful" visit, at a time when President Donald Trump is floating the idea of making his northern neighbour the 51st US state. The 76-year-old monarch, who is also Canada's head of state as part of the Commonwealth, has never publicly commented on the ambitions of the US president, a noted admirer of the royal family.

“Crafted in silver and embellished with diamonds, it’s adorned with the regiment’s iconic bugle horn cap badge. The brooch was presented to her in 2012 by General Sir Patrick Sanders, then Colonel Commandant of The Rifles, to mark her appointment as colonel-in-chief,” Stone said.

“Since then, Queen Camilla has worn it on numerous ceremonial occasions, including during official visits to Canada. I’d estimate it to be worth around £100,000.” (100,000 pounds equals roughly $135,095.) Queen Camilla has an extensive jewelry collection, often wearing brooches for particular public royal engagements.

Along with her own collection of jewels, the queen consort inherited several pieces from the late Queen Elizabeth II’s collection, following the monarch’s death in September 2022. In April 2024, Queen Camilla wore Queen Elizabeth II’s regimental brooch, featuring the skull and crossbones symbol.
