The Countess of Wessex is one of the most stylish members of the royal family and we love it when we get the chance to see Sophie in a tiara.The first time, of course, was for her wedding to Prince Edward in 1999.
The 'Anthemion' tiara was gifted to the bride for her big day and is known to be made up of a number of antique pieces from the Queen's collection.
It's become Sophie's signature tiara and Her Majesty's dresser Angela Kelly confirmed in her book The Other Side of the Coin: the Queen, the Dresser and the Wardrobe, that the headpiece was redesigned by jeweller Harry Collins for Sophie to wear at the State Banquet with President Trump in 2019. But it's not the only jewels that we've seen on the Countess, take a look through HELLO!'s gallery to see all the times Sophie has wowed in a tiara.

Sophie joined the Queen and the Duke of Edinburgh as they hosted King Abdullah II and Queen Rania of Jordan for a state banquet at Windsor Castle in 2001. She can be seen at the top of the photograph wearing an embroidered blue gown with the Anthemion tiara, and diamond necklace and earrings.
Sophie wore the headpiece for Princess Martha Louise of Norway and Ari Behn's wedding in 2002, teaming it with an elegant strapless monochrome gown and diamond jewellery.
In 2004, Sophie debuted a new diamond floral button headpiece with a dark grey ruched gown, to Prince Frederik of Denmark and Mary's pre-wedding gala. The origins of the headpiece are still unknown, but it's thought to have been a loan, and hasn't been seen on the Countess since. She also wore her Royal Family Order honour awarded to her by the Queen the same year.
For Prince Frederik and Mary's wedding in 2004, Sophie pulled out all the stops in a hot pink off-the-shoulder gown with the Anthemion tiara perched on her chic updo.
In 2005, the Countess debuted a third tiara with a large central aquamarine set among a diamond scroll frame. She wore it with a cream beaded v-neck gown to the enthronement dinner ceremony of Prince Albert II of Monaco. As it's never been seen before on another member of the royal family, it's assumed that the piece is part of Sophie's private collection.
For a charity gala dinner in 2006, Sophie debuted the aquamarine tiara in its convertible necklace form with a black v-neck evening gown.
