The Jeweled Crown is a Special Loot item found in Sly 2: Band of Thieves. It is a Booby Trapped Loot, so Sly has to bring it back to the Safe House before time runs out. Once at the Safe House it can be sold on ThiefNet for 652 coins. It is in one of the graveyards underneath the Re-Education Tower (while facing the fence, the Re-Education Tower is on the left side).
