Trivia / The Jewel Kingdom

• Feelies: The original version was famous for including costume jewelry with its first print run: necklaces for the first four books, rings for the next four, and a bracelet in the super special, each with plastic jewels matching the shape and colour associated with each princess. The 2020 reprint includes sparkly stickers instead.
• Pop-Culture Urban Legends: Even the Google Books page for The Jewel Princesses and the Missing Crown perpetuates the long-held misconception that the final book adds four new Jewel Princesses. It doesn't. The other four gems on the cover are just meant to represent the Great Jewelled Crown.
  • Also, the rumour that the short movie was a Poorly Disguised Pilot for a show adapting all the books. The authors have never confirmed or denied it.
• Self-Adaptation: One of the authors directed The Film of the Book and both did the script for it.
