It’s Queen against Queen in this afternoon’s tiara showdown…

The Vladimir Tiara vs. The Belgian Sapphire Tiara

The Vladimir Tiara

Classic design? Check! Multiple settings? Check! Incredible backstory? Definitely check! The Vlad’s a top seed in this tournament for a reason — it checks all the boxes! The Queen’s been wearing it since 1953, and it’s rightfully become one of her signature pieces.

The Belgian Sapphire Tiara

When the Queen needed a sapphire tiara in the ’60s, she bought a necklace formerly owned by a Belgian princess and had it put on a tiara frame. The result is this sparkler, which fills an important hole in her collection — but has garnered mixed reviews from tiara lovers. Can it take down the mighty Vladimir???

Check back for one more tiara match-up here later today!

This match-up between a diamond festoon and a diamond crescent promises to be a fascinating one…

Princess Anne’s Festoon Tiara vs. The Teck Crescent Tiara

Princess Anne’s Festoon Tiara

This delicate diamond festoon tiara was given to the Princess Royal in 1973 when she christened a ship. (Not a bad thank-you present!) It’s intricate and pretty, which made it a perfect wedding tiara for Anne’s daughter-in-law in 2008. Will its romantic design carry it to victory?

The Teck Crescent Tiara

It’s been almost a century since we’ve seen a British royal wear this tiara, but we know it’s currently on loan to the Duchess of Cornwall. Made in the nineteenth century, the diamond sparkler combines rose and crescent elements that belonged to Princess Mary, Duchess of Gloucester (a daughter of King George III!). Can this hidden royal sparkler cause a tiara upset?

Stop by later this afternoon for our third tiara tournament game of the day!

Our first sparkling match-up of the day pits a classic royal tiara with a more modern diadem…

The Lotus Flower Tiara vs. The Aquamarine Ribbon Tiara

The Lotus Flower Tiara

This charming diamond and pearl tiara, made in the 1920s, originally belonged to the Queen Mother. It later became one of Princess Margaret’s signature pieces, and now it’s worn by the Duchess of Cambridge. Its delicate design and gorgeous Egyptian-inspired motifs make it a major contender for a title.

The Aquamarine Ribbon Tiara

The background of this tiara, which features five bright blue aquamarines surrounded by curling diamond ribbons, is a bit of a mystery. It was worn by the Queen in the 1970s, and more recently, it’s resurfaced on the Countess of Wessex. Unabashedly ornate and cheerful, this tiara could give the Lotus Flower a run for its money!
