Happy Halloween, magpies! To celebrate, I’ve got an updated top ten list for you: the very maddest tiaras from royal collections. From spooky to downright confusing, these are some of the strangest sparklers of all…

10. Queen Louise’s Aquamarine Bandeau: The hunt for the maddest tiaras makes its first stop in the Bernadotte family vaults in Sweden, where this simple yet strange bandeau resides. It’s the tiara given to Princess Madeleine for her eighteenth birthday, and for many years, it was one of the only tiaras she wore. The piece is actually an heirloom, but that hasn’t stopped many royal watchers from affectionately (or not?) dubbing this one “the Cyclops.”

9. The Aquamarine Pineflower Tiara: This Cartier-made tiara, which includes pinecone elements mixed with large rectangular aquamarines, was once owned by the Queen Mum. Not surprisingly, it’s not been high on the “most-worn tiaras” list for either the QM or her granddaughter, though Anne has worn it occasionally (and attempted a slight redesign).

8. The Burmese Ruby Tiara: A relic of the interesting jewelry design era that was the 1970s, the Tudor roses in this modern tiara unfortunately read “big red blob” far too often for this one to be anything but a mad diamond and ruby experiment gone wrong.

7. The Swedish Four-Button Tiara: Beep, beep, everybody — it’s the Jeep! The diamond buttons on this one are family heirlooms (and gorgeous diamond pieces individually), but sadly, the combination of the four together definitely reads “headlights.”

6. The Chaumet Emerald Tiara: The grand ducal family of Luxembourg has some stunning pieces of jewelry tucked away in their palace vaults … and then they also have this tiara, suitable for Wonder Woman’s fanciest gala appearances. (The egg-sized emerald almost saves it, though!)

5. The Teck Ears of Wheat Tiara: Tiaras featuring ears of wheat designs are often a little difficult to pull off, but at certain times, this classic British royal example of the genre reads more than a little like skeleton fingers. Eek!

4. Queen Sonja’s Modern Gold Tiara: It’s just never good when a queen consort’s tiara would look right at home on the set of a sci-fi flick — and even worse when one of the central element options looks uncomfortably like an ant!

3. The Albanian Sapphire Ram Tiara: When your national symbol is a helmet topped by a ram, you’re in for some interesting tiara designs. This sapphire ram tiara is definitely an original!

2. Princess Astrid’s Aigrettes: According to Astrid herself, she’s pretty sure she can pick up radio signals from across Europe with her two diamond aigrettes — the diamond wing tiara and the one that looks like ruby and diamond antennae!

1. Queen Margrethe II’s Golden Poppies: Not so much a tiara, really, as an experience — and by “experience,” I mean a giant creepy gold headdress made of flowers and bugs. It’s another relic of the 1970s, when tiara makers got terribly creative. I don’t know, though — it’s Daisy, after all. If she’s not going to wear a truly mad tiara, who will???
