Camp Necklace

The Camp Necklace is given to each camper at the end of each summer at Camp Half-Blood. The cabin senior counselors vote on the biggest event of the summer and paint it on a bead.

Beads
The Lightning Thief - A black bead with a green trident. Percy's first year.

The Sea of Monsters - The golden fleece. Percy's second year.

The Titan's Curse - There was no bead. The events of this book took place in the same year as the Sea of Monsters, during the winter.

The Battle of the Labyrinth - An intricately designed maze to represent the Labyrinth. Percy's third year.

The Last Olympian - The Empire State Buildingwith the names of the deceased in tiny Greek letters. Percy's fourth year.

There are five beads on Annabeth's necklace at the start of The Lightning Thief, from years before the books. The ones said were Thalia's tree, centaur in a prom dress, and a greek trireme on fire. Percy inturupts her, so the last two are unknown. It is assumed Luke has the same set.
