Queen Maxima and Crown Princess Mary Sparkle in The Hague

Crown Prince Frederik and Crown Princess Mary of Denmark are currently on an official visit to the Netherlands, and on Monday evening, they joined King Willem-Alexander and Queen Máxima at a Dutch-Danish trade dinner at the Grote Kerk in The Hague. The two couples are contemporaries, but the Dutch royals are reigning monarchs, which leads to fun photographs like this one, showing Crown Princess Mary curtseying to Queen Máxima.

The men wore business suits and the women wore cocktail attire for the dinner. Queen Máxima wore an elegant black dress with an off-the-shoulder neckline and a modern belt detail.

She accessorized with diamonds and pearls. Her large diamond stud earrings are the top portion of Queen Wilhelmina’s Diamond Earrings, which date to 1889. (They’re part of a collection of jewels that also includes the Dutch Diamond Festoon Tiara.) The focus piece of her jewelry for the evening, however, was the grand five-stranded pearl necklace with the pearl and diamond clasp. The necklace is a longtime favorite of Máxima’s mother-in-law, Princess Beatrix.

Máxima wore her diamond wedding bracelet on her right wrist and her diamond family initial bracelet on her left.

Crown Princess Mary also chose a black dress for the evening. The dress used to be a longer evening gown, but it was shortened for a previous occasion. Mary paired the dress with striking yellow Manolo Blahnik heels.

The sparkling earrings she wore with the ensemble combine a diamond-set floral stud with a pale briolette drop. I believe the drops were previously worn with a different stud at Royal Ascot in 2016. The floral portion looks similar to (but not the same as) a pair of Ole Lynggaard Copenhagen earrings from Mary’s collection.

Mary wore gold and diamond bracelets on both wrists. And check out that enormous ring on her right hand! The yellow-hued gemstone coordinates with her shoe choice for the event.
