Features the Empire State Building with the names of the campers who fell in the Battle of Manhattan in tiny Ancient Greek writing. This was given to the campers on completing their summer at Camp Half-Blood. The bead represents the most memorable event of that year, the Battle of Manhattan against Kronos' army, the terrible casualties and honor to the loved ones lost.
It does not mention a bead being made because it was in the winter, during the same year of The Last Olympian.
No bead was mentioned as this story focuses on the Roman campers at Camp Jupiter and they do not give beads, instead burn a new line on the tattoos on the arms of their campers.
Most of the journey in the book was spent away from both camps as the Seven sail back to the Ancient Lands. This is also due to the fact that the book took place between June 25th and July 1st, but camp beads are only given out at the end of the summer session every year, usually in the middle of August.
There are five beads on Annabeth Chase's necklace at the start of The Lightning Thief, from the years before Percy Jackson's arrival at Camp Half-Blood. The beads she mentioned were the ones featuring Thalia's pine tree for her first year at camp, a Centaur in a prom dress, and a Greek trireme on fire. Percy interrupts her, so the last two of her beads are unknown. Annabeth also has her father's college ring on her necklace. In The Mark of Athena, it is mentioned that Annabeth was given a red coral pendant by Percy to her when they started dating. Percy got the coral for her from Poseidon's Palace.
Percy has four beads total on his necklace, along with other items he has received at different times.
In The Last Olympian, Percy put his father's gift, a sand dollar, on his necklace and later gives it to the Hudson River and the East River. In The Son of Neptune, Percy put his Probatio tablet on his necklace. At one point in the book Percy loses his necklace to Queen Hylla, and later gets it back from Hazel Levesque.
- Annabeth Chase has more camp beads than any other known demigod.
- Interestingly, none of the official images of any campers see them wearing their camp necklaces in the artwork by Antonio Caparo.
