King Willem-Alexander and Queen Maxima of the Netherlands visited Bremen on Wednesday, and Maxima chose jewels very fitting for a royal lady from the House of Orange.

Maxima accessorized her navy and burnt orange ensemble in Germany with fabulous earrings from her extensive collection of orange jewels.

The earrings feature large orange gemstone drops, perhaps topazes or citrines. (See our previous post on her collection of topaz/citrine jewels over here!)

Here’s a slightly better view of the earrings, which emphasizes both their vivid color and the size of the drop.

We also caught a glimpse of Maxima’s bracelets, including the bracelet featuring the diamond-set initials of her husband and daughters.

Overall, the orange jewels helped to tie together the colors of Maxima’s outfit. You know that I love any excuse to wear a bright, beautiful gemstone — somehow I think Max agrees with me!

With one of the most extensive jewelry collections in Europe, it’s no surprise that the Dutch royal family owns a large number of excellent aquamarine pieces. Today, we’ve got a closer look at one of the sparkliest: Queen Juliana’s Aquamarine Pendant.

The pendant features a large, pear-shaped aquamarine in a vivid shade of bright blue, surrounded by a thin border of diamonds. The gem was one of the gifts that the future Queen Juliana of the Netherlands received when she married Prince Bernhard of Lippe-Biesterfeld in January 1937.

Juliana usually wore the pendant on a thin white-gold chain, which is studded with additional diamonds. It fit perfectly into her collection of sautoir-length necklaces.

Although it is a large, glamorous piece of jewelry, Juliana wore it for both casual daytime engagements and more formal evening occasions, often pairing it with other pieces from her aquamarine collection.

She also sometimes layered the piece with additional long necklaces. In 1969, during a visit from President Pompidou of France to The Hague, Juliana paired the aquamarine pendant with pearls.

The aquamarine continued to be one of her favorite pieces of jewelry throughout her reign. In the image above, she wears it for one of her last Prinsjesdag appearances. Three years later, she wore it for the inauguration ceremony of her daughter, Beatrix.

Even though it was a favorite personal piece, Juliana did occasionally loan the aquamarine pendant out to her second daughter, Princess Irene. Here, you’ll spot the aquamarine (worn on a shorter chain) tucked just under the neckline of Irene’s gown.

The aquamarine is also easy to spot on Irene here, worn during the premiere of Juliana in Zeventig Bewogen Jaren in Amsterdam near the end of Juliana’s reign.

And during the inauguration festivities for her nephew, King Willem-Alexander, Irene took the aquamarine out for another spin, wearing it for the water pageant that followed the official inauguration ceremony.

After her mother’s death, Princess Beatrix also began occasionally wearing the pendant, which is now part of the family’s jewelry foundation. Here, during a visit to Turkey, she uses the pendant as an enhancer on a classic diamond riviere.

And in recent years, Queen Maxima has become the most frequent wearer of the piece, usually suspending it from one of the family’s diamond bow or ribbon brooches. She wore the pendant with this delicate bow brooch in Spain in 2013…

But my favorite appearance of the aquamarine in recent years came in April 2013, when Princess Laurentien wore it for the dinner held the night before her mother-in-law’s abdication (and her brother-in-law’s inauguration). She wore the pendant suspended from a portion of the grand diamond stomacher that belongs to the Stuart Parure. Inventive and gorgeous!
