7. Queen Sofia of Spain, God bless her, piled on the jewels — pearl earrings, pearl necklace, paired brooches, plus bracelets and watch — to mark the 40th anniversary of a hospital named in her honor in Cordoba on Monday.

6. King Harald and Queen Sonja of Norway are on a state visit to Italy this week. She wore a pearl necklace and bracelet, plus a delicate ribbon-shaped brooch, to Palazzo Chigi for a visit with the prime minister on Wednesday.

4. Queen Letizia wore an absolutely gorgeous pair of diamond floral earrings at a ceremony for honorary doctorate recipients in Salamanca on Tuesday.

3. Back to the state visit jewels: Queen Sonja wore an ultra-modern suite of metallic jewelry to lay a wreath at Italy’s Tomb of the Unknown Soldier on Thursday.

2. And on Wednesday, Sonja went for a major statement necklace and a stack of bangles for a meeting with the president of Italy’s senate.

1. But of course, it’s the state visit tiara that wins it for me this week: Sonja wore the small version of Queen Maud’s Pearl Tiara 2.0 — and the Drapers’ Company Brooch! — for the state banquet on Wednesday evening. I actually think the full version of the tiara suits her better, but I’m not going to look a tiara gift horse in the mouth!
