Day Four of King Willem-Alexander and Queen Maxima’s visit to Australia saw the royal couple touring various sites in Sydney. Unfortunately, the visit also broke our streak of major jewels for the trip.

Maxima wore an outfit by Natan, and her earrings and necklace were also costume pieces from the brand.

Here’s a closer look at the necklace, which she debuted in June 2015.

We did see one piece of fine jewelry, although it was a little tough to spot. In the detail shot above, you can see that Maxima wore a large ring on her right hand. This is the citrine and diamond ring that Willem-Alexander gave her after the birth of Princess Alexia.

King Willem-Alexander and Queen Maxima wrapped up Wednesday’s part of their tour of Australia with a concert at Sydney’s famed Opera House. For this evening event, Maxima continued this state visit’s trend of major jewelry.

With her evening gown, Maxima wore the diamond and emerald earrings from her own personal collection. She paired the earrings with a jewel from the Dutch royal collection: a diamond riviere, from which she suspended the large brooch from the emerald parure. To that brooch, she attached an enormous cabochon emerald drop. This emerald has been in the family for quite a long time, possibly dating back to the late 18th century.

Maxima also wore the diamond and emerald-studded bracelet from the emerald parure. The piece is an open-work creation. She’s also wearing a large ring on her right hand; I believe it’s the ring from the emerald parure.

I am all starry-eyed over the emeralds, but I will admit that I’m not the biggest fan of the dress. I’d have loved to see these pieces against a solid navy-blue gown.

The Dutch state visit to Australia continued in Canberra on Wednesday, where King Willem-Alexander and Queen Maxima had tea at Parliament House and visited Australia’s war memorial.

Maxima went full orange for the daytime engagements, in both dress and jewels. Above, you can see that she wore earrings set with yellow and orange gemstones. I’d wager that these are part of her collection of citrine jewels.

She also wore her large bracelet set with various shades of citrines…

…and an enormous cocktail ring, also set with various shades of orange gemstones. Very appropriate for the wife of the head of the House of Orange!
