Our Magpie of the Month, Princess Astrid of Belgium, is a huge fan of Chanel. You’ll often see her sporting clothes and handbags from the fashion house — and, as we’re discussing today, jewelry! Here’s a closer look at one of her most eye-catching Chanel necklaces.

Astrid wore this long pearl station necklace, plus other clothing and accessories by Chanel, for the wedding of her elder son, Prince Amedeo, to Elisabetta Rosboch Von Wolkenstein at the Basilica Santa Maria in Trastevere in Rome in July 2014. You’ll note that the necklace also features two more additional embellishments: the famous interlocking Cs that make up the brand’s logo, as well as a brooch-like ornament that resembles a pearl cluster with a square central stone.

You can see the necklace peeking out of the collar of Astrid’s jacket in this photo, taken at a UN reception in Brussels a year and a half later. She’s also wearing the same pair of earrings, which she generally pairs with the necklace: a stud made of a trio of diamonds from which a pearl drop is suspended.

The earrings and necklace also made an appearance last summer in Seoul during Astrid’s ten-day economic mission to South Korea. You can spot the Chanel logo peeking out of her jacket on her right side, and the brooch-like ornament positioned near her heart on her left side.

The long necklace appears to move with the wearer — in this photograph, taken at a different event on the same day in South Korea, the brooch-like ornament has flipped, with the silver-toned back of the embellishment visible just under Astrid’s jacket.

With the royal wedding behind us, it’s time once again to spend the month focusing on the jewelry collection of one royal in particular! Our Magpie of the Month for June is an elegant continental royal: Princess Astrid of Belgium, daughter of one king and sister of another. Today, we’re looking at one of my favorite pairs of earrings from her jewelry box: her square-cut diamond drop earrings.

The striking earrings feature a trio of stones: a pear-shaped diamond stud, from which a small square stud (turned on its edge, like a diamond) and a larger square-cut drop are suspended. Astrid has been wearing the earrings consistently for at least a decade.

It’s no surprise to me that these have been consistent favorites in Astrid’s jewelry box for such a long time. The classic style of the earrings means that they work well with lots of different outfits and for various occasions. For example, she wore them with a (very interesting) feathered hat for a service of remembrance in 2010…

…and with a more casual, neutral ensemble for the dedication of a new church a year later. I think the earrings look especially lovely with outfits like this one, which feature clothing with classic lines in soft colors.

In 2013, Astrid packed the earrings — or, at least, she packed one of them — for a trip to India, where she participated in a mission focused on economics and trade. For a memorial commemorating the anniversary of the deadly terror attacks in Mumbai, Astrid wore one of the earrings from this pair in her right ear. Look closely, and you’ll see that she wore a different diamond earring (with a similar length but a differently-shaped drop) in her left ear. Astrid often takes chances wish fashion, but for such an important memorial event, I doubt she was concerned with making a jewelry statement — so I think this was just an error, perhaps the result of changing her outfit too quickly between engagements.

Although you’ll sometimes hear etiquette experts suggesting that diamonds should only be worn in the evening, a good pair of classic diamond earrings can be a lovely companion to a daytime outfit. Indeed, Astrid generally wears this pair of earrings in the daytime, as she did during a visit to a hospital in 2016.

A recent appearance for the earrings came in October 2017, when Astrid accompanied the Duke of Cambridge to Flanders for events commemorating the contributions of soldiers from New Zealand in the Battle of Passchendaele. Though they feature large stones, the earrings don’t pull focus at a somber event like this one — making them a very important option in a princess’s jewelry box.
