This Week in Royal Jewels: March 7-13

10. Queen Sofia of Spain chose pearls and a gold brooch for an “In Memoriam” tribute concert in Madrid on Wednesday.

9. Crown Princess Victoria of Sweden celebrated her name day on Wednesday with a pair of modern silver earrings and an especially adorable guest: Princess Estelle.

8. On Wednesday, Queen Elizabeth II chose her ruby and gold floral brooch for a visit to the Royal Commonwealth Society. The brooch may have been one of her wedding gifts, possibly from the people of Monaco.

7. Crown Princess Mary of Denmark wore low-key jewels on Sunday during a visit to New York, where she attended a dinner hosted by the Consul General of Denmark.

6. The Duchess of Cornwall wore her four-strand pearl necklace, reportedly a Parker-Bowles family heirloom, at a service at Westminster Abbey honoring the late Sir David Frost. (Other royals and royals-adjacent also attended, including the Countess of Wessex, Princess Beatrice, Lady Sarah Chatto, Viscountess Linley, Crown Princess Katherine of Serbia, Pippa Middleton, and Sarah, Duchess of York, who ably channeled the Flying Nun for the occasion.) Camilla wore the same jewels at the Abbey earlier in the week for the Commonwealth Observance Service.

5. On a visit to Peru on Friday, Queen Maxima fancified a casual daytime look by adding a brooch from the Mellerio ruby parure.

4. Queen Mathilde of the Belgians was welcomed to Buckingham Palace by various members of the Windsor family on Thursday; she wore sparkling pearl and diamond earrings for the occasion.

3. At the Commonwealth Observance Service, the Queen wore one of her most frequently-sported brooches: the Frosted Sunflower, made for her in the 1970s by Garrard.

2. Continuing her celebration of Commonwealth Day, the Queen sparked a bit of a jewel mystery when she wore this unidentified brooch to a reception at Marlborough House.

1. And, last but not least: Princess Marie of Denmark finally debuted the Flora Danica Tiara this week! (At the same event, a government dinner, Queen Margrethe wore the floral aigrette, Crown Princess Mary wore her wedding tiara, and Princess Benedikte wore her floral birthday tiara.)
