While the Danish princes went with flag rings, Prince Willem-Alexander went with a ring in his national color. The central diamond is an orange hue, a fitting gift from the Prince of Orange. Willem-Alexander had a hand in designing the unusual ring, placing the diamond horizontally and surrounding it with two white diamonds on either side and a white diamond band above and below.

Grand Duchess Maria Teresa of Luxembourg
Hereditary Grand Duchess Stéphanie of Luxembourg
The ring Guillaume gave Stéphanie reminds me a bit of Beatrix's ring, with its double outside rows. It may be just that method of creating a larger ring that puts this one near the top of my favorites list. Stéphanie has also worn her mother's engagement ring, particularly around the time of her wedding - her mother, of course, died just weeks before these two married.
After her engagement to Prince Félix of Luxembourg, Claire Lademacher was spotted in this ring, a diamond with a hefty diamond band.
