Queen Camilla shines in her new favorite tiara for Buckingham Palace reception.

Just now, Queen Camilla had another glamorous moment.  

The 76-year-old Queen looked stunning at the Diplomatic Reception held at Buckingham Palace on Tuesday evening.  

Hundreds of Diplomatic Corps members are welcomed to the royal residence in London by members of the royal family for the yearly white-tie event.  

At the palace ceremony, Queen Camilla was accompanied by Prince William, Kate Middleton, and King Charles.  

Reaching up to 1,000 people, it's one of the biggest parties at Buckingham Palace, according to the Royal Collection Trust.   

"The invitation list is coordinated by the Marshal of the Diplomatic Corps and invitations are sent to all the ambassadors and high commissioners at the foreign missions in London, as well as past Prime Ministers, the Archbishops of Canterbury and York and other public figures," they said.  

Queen Camilla paired the Girls of Great Britain and Ireland Tiara with her white gown.  

Less than two months ago, Victoria made her debut wearing the tiara when she and King Charles went to Mansion House to participate in customs that mark a new monarch's first visit to the City of London.
