Peridot
- Gem: Peridot
- Weapon: Unknown
- Known fusion: None
Peridot (voiced by Shelby Rabara) – A Homeworld Gem with a cranky, business-like personality. She is also extremely intelligent, more so than any other known gem. Her gem stone is a triangular peridot embedded on her forehead. She possesses the ability to spawn a holographic interface and control spherical "robonoids" of varying sizes (which appear to assist her in her maintenance duties like repairing broken warp pads) and other equipment (such as an energy cannon); she can also spin her fingers around to function like a helicopter's propeller for the purpose of flight.
The Crystal Gems first see her arriving at the Earth terminal of the Galaxy Warp with the intent of performing a maintenance check on it. After sending a series of probes in an attempt to remotely reactivate Earth's Kindergarten, and then discovering the existence of the Homeworld Gems ("Marble Madness"), she travels to Earth with Jasper and Lapis in person via a hand-shaped spacecraft.
As her ship was about to crash-land on Earth near the end of "Jailbreak", Peridot was able to escape in her own pod, which was later discovered by Steven, Jenny Pizza, Buck Dewey, and Sour Cream in "Joy Ride". She appeared once again in "Keeping It Together", where she was performing unorthodox fusion experiments in the Kindergarten, "Cry for Help", where she sent a distress signal to the Gem homeworld through the Gem communication tower, and "Friend Ship," in which she traps the Crystal Gems in an ancient Gem ship with the intent to destroy them.
As of "Friend Ship," she is missing her left foot, having detached it in order to escape the Crystal Gems. As the series has progressed and she has remained trapped on Earth, her sanity has apparently started to deteriorate.
