The lit emerald lantern is a light source used during the Lunar Diplomacy quest. It is created by lighting a emerald lantern with a tinderbox, requiring level 49 Firemaking. If lost, the emerald lens can be recovered by speaking to the Cabin Boy who can be found slightly north-west of the Lunar Isle bank.
During the quest, the item is used to uncover markings on specific objects around the Lady Zay which have been jinxed by the Cabin Boy (uncovered during the quest).
This lantern cannot swap the emerald lens with bullseye lantern, as the sapphire lantern can.
