The Corrupting Light, was a weapon utilized by the Great Diamond Authority, as a means of corrupting the remaining Gems on Earth, near the end of the Rebellion. This light was first shown in "Same Old World" and later explained in "Monster Reunion". The light is composed of blue, white, and yellow rays, potentially referencing the diamonds of the same color.


Same Old World Homeworld Flee

In "Same Old World", Lapis states that there was a panic on Earth to escape after all hope of stopping the Rebellion was lost. After the majority of Homeworld Gems fled, a light was emitted from the sky. Later, in "Monster Reunion", the purpose of the light was explained by Centipeetle as a tool for corruption, most likely to ensure the rebellion could never threaten Homeworld, as well as an indirect way to destroy all life on the planet by way of the out-of-control monsters. Based on her recollection of the event, it is most likely that the majority of Gems were not aware of what exactly they were fleeing from.


  • Steven described the light as: "A sound? A song?".
  • Despite all Gems exposed to the light being corrupted, Lapis was unaffected for unknown reasons.
    • The Desert Glass was also trapped similarly, but became corrupted.
