We’re wrapping up our focus on the jewels of January’s Magpie of the Month, Queen Mathilde of the Belgians, with a look at a very fun — and very sparkly! — pair of diamond earrings from her jewelry box.

These earrings, which feature diamond loops and scrolls, plus a diamond drop, were made by Cartier. Mathilde has had them in her collection for at least a decade.

A major early appearance for the earrings came at Belgium’s National Day festivities in 2007. She also wore them that year for the commemoration of the 90th anniversary of the Battle of Passchendaele.

The following year, she wore the earrings for a visit the Brotherhood of St. Sebastian in Bruges, pairing them with an embroidered jacket.

The earrings were a lovely accessory for Mathilde during the official November 2016 visit to the Netherlands. She chose them for her visit to the Sligro Foodgroup Netherlands in Veghel.

One of the highest-profile outings for the earrings, though was their appearance at the National Day concert in July 2013, which took place on the day before she became the country’s queen consort.

Our Magpie of the Month, Queen Mathilde of the Belgians, has an impressive collection of earrings, but few pairs have remained favorites as long as today’s earrings, her Diamond Scroll Earrings.

The diamond earrings have been in Mathilde’s jewelry box for about fifteen years. They were reportedly purchased for her by her husband, King Philippe, from the Belgian jewelry firm Leysen. Mathilde began wearing the earrings in 2003, and one of her early important appearances in the pair came at the Danish royal wedding in 2004.

The earrings feature a trio of white diamond scrolls, each with a yellow diamond set in its center. I’ve seen some remark that the earrings resemble the letter “E” — I’m not sure if that’s intentional, but if it is, the earrings might have been a gift following the birth of their eldest child, Princess Elisabeth, who is now the Duchess of Brabant.

I’ve also seen speculation that the yellow diamonds in the earrings can be swapped out for other stones. This appears to hinge on a single appearance in Shanghai in November 2004, when Mathilde wore the earrings for a gala dinner with a dark green gown. In some photos from the event, the larger stones in the earrings do appear to be darker, but I’m not convinced that it isn’t just a trick of the light. If the earrings were convertible, I imagine we might have seen Mathilde experiment with them a bit more.

Mathilde has mainly used the earrings for glittering gala occasions, both with and without tiaras. They’re not huge, but the earrings pack enough sparkle that they easily work as spotlight accessories with an outfit.

They also coordinate well with Mathilde’s tiaras. Above, she wears the earrings with her laurel wreath tiara during the German state visit in March 2016.

Although Mathilde primarily reserves the earrings for evening events, she’s also occasionally worn them for important daytime occasions. Here, she pairs them with Queen Fabiola’s Diamond Fringe Brooch at the wedding of her husband’s cousin, Hereditary Grand Duke Guillaume of Luxembourg, in October 2012.
