Peridot has light-green skin and eyes tinted green by her visor. Her fingers are not directly attached to her body, but instead levitate around where her palm would be. Peridot's hair is yellowish green, and styled into a tetrahedron shape. A light-green visor covers half of her face. She wears a sleeveless, green, V-neck bodysuit, large boots, and armguards. Her bodysuit is mostly medium green, with a dark-green diamond outline around the cut out of her neck area; meeting together to a pale-yellow diamond symbol at the front, below the diamond symbol, with a dark-green portion between her chest and leggings. Peridot's sleeves/armguards and boots are light-green, and with dark-green portions, with yellow, diamond-shaped knees and elbow pads. Her gem is located on her forehead, and is shaped like an inverted triangle with rounded edges.
Thus far, Peridot has been shown to be cold and ruthless. She takes her work seriously, crushing one of her Robonoids when it was damaged in "Warp Tour". In "Marble Madness", she shows herself to be slightly arrogant, and she does not have a high opinion of humans. She attempts to crush Steven after briefly interrogating him.
Despite her cold nature, Peridot is easily flustered. She also seems to be rather childish when things do not go her way. When Peridot realized that the Crystal Gems were the ones that have been destroying her equipment, she quickly lost her temper and asked "Why do you keep destroying my things?!". She also complains to herself when Jasper disregards their mission directives and instead chooses to return to Homeworld.
Peridot also seems to be very naive when it comes to Earth, especially when the information is not important to the mission, such as assuming that Steven's Crying Breakfast Friends! sticker was a sign to show that the Galaxy Warp had been compromised. She also believed that, while interrogating Steven, there were a species called "Stevens", just because he addressed himself by his name.
In "Keeping it Together", her personality seems much more crazed than in previous appearances. For example, when flying away with her helicopter fingers, she smiles down and laughs, and her facial expressions are exaggerated throughout the episode. This is possibly due to her being in isolation in Kindergarten since her escape in "Jailbreak". However, she spoke to Steven far more calmly, most likely recognizing him as a minimal threat compared to the other Crystal Gems.
In "Cry for Help", Peridot interrupts Crying Breakfast Friends!. She sends a message to Yellow Diamond through the Communication Hub, begging for help. Peridot seems much more worried and/or scared than crazed for the brief moment she appears. She does not seem to be worried about her informant or her escort much.
Peridot has a high intellect, manipulating Gem technology with ease. Her hand to hand combat abilities, however, are questionable, as she was defeated by Amethyst, but may have been outnumbered. She is shown to have variety of evasion tactics, along with being able to survive a great fall in "Keeping it Together".
- Interface Creation: Peridot can project a holographic touchscreen from her fingers, in which she can control and connect to different forms of Gem technology.
- Wall-Scaling: Peridot can freely run up vertical walls.
- Helicopter Fingers: Peridot can whirl her fingers to fly.
- Electrokinesis: Peridot can generate electrical currents through her fingers.
- Gem Destabilizer: Like Jasper, Peridot wields a Gem Destabilizer, an extremely potent, non-lethal tool used to subdue enemy Gems.
- Robonoids: Peridot can create different types of spherical robots, known as Robonoids. There are three types of known Robonoids: Flask, Plug, and Hand. They can perform multiple functions, such as healing a Warp Pad and activating the Gem Kindergarten.
- EMP device: In "Warp Tour", Peridot placed a device on the Galaxy Warp Pad before she left Earth. About three seconds after being placed, the device explodes, disabling all of her Robonoids. The device seems to be highly advanced, as Pearl's machine (which appears to be made from human technology) was unable to disable even a single Robonoid.
At first, the Crystal Gems didn't know who Peridot was. But they all (except Steven) seemed to be afraid of her (as shown when they hid from her in "Warp Tour" and "Marble Madness"), though it might have been out of the fact that none of them knew what she was capable of. Likewise, Peridot wasn't aware that any Gems remained on Earth, much less the Crystal Gems, as she was quite shocked to find them still alive. In "The Message", Lapis Lazuli told the Crystal Gems that a Gem with advanced technology (whom Pearl assumes to be Peridot) would be bringing an army to Earth and that they should surrender, as it would be much easier. In "Joy Ride," Garnet does seem to have a bitter resentment after the events of "Jail Break," as she and the other Crystal Gems relentlessly attacked and beat her Escape Pod when they thought she was inside. In "Keeping it Together", she seemed to fear them and called them "Crystal Clods", running from them in shock, and only fought back when tied up.
Peridot has a ruthless attitude toward Steven, viewing him as less than a threat and more like a human. This arrogance has caused her to underestimate him on numerous occasions. When Peridot first saw Steven in "Marble Madness" she thought there was an infestation of "Stevens" in the Kindergarten. Peridot then asked him if "Stevens" were the dominant species replacing humans before attempting to crush him with a giant fist, only to be stopped by the other Crystal Gems. In "The Return", she continued to show little regard for Steven, who was believed to only be a human, until it was revealed that he was actually Rose Quartz (or so she and Jasper believed). In "Jail Break", Peridot attempted to use her Gem Destabilizer to subdue Steven, and was surprised by his apparent immunity to the effects of the device. In "Keeping it Together", she talks to Steven calmly with only a hint of fear (Likely due to his connections with the Crystal Gems). However, she runs away shortly when the rest of the Crystal Gems find her.
Though the extent of their relationship is unknown, Jasper seems to be Peridot's superior, as Peridot calls on her for back-up. Peridot followed Jasper much to her displeasure, while the latter dismissed her complaints and her issues as trivial. It is very clear that Jasper thinks less of her. It is revealed in "Cry for Help" that Jasper is her escort.
In "Cry for Help", it is revealed that Lapis is Peridot's informant, implying that they have actually interacted off-screen.
In "The Return", when Jasper mentioned the name Yellow Diamond, not only Lapis winced, but Peridot showed fear as well. Yellow Diamond seems to be her superior, since Peridot sends a help message to her.

- Peridot is the only Gem with non physically-attached body parts; in this case, her fingers.
- Peridot was the second Homeworld Gem to appear on the show, right after Lapis Lazuli.
- Similarly to Lapis Lazuli and Jasper, Peridot has a diamond on her uniform.
- This trend appears to occur on Homeworld Gems.
- Based off of the loud pounding of her footsteps, it can be assumed that she has an unusually large mass.
- Peridot appears to have an almost limitless supply and variety of Flask Robonoids, as she was able to deploy numerous amounts and at any size.
- Her final words before her screen faded out in "Marble Madness" were, "I'm reporting this!", implying she has a supervisor.
- In "The Message", Lapis Lazuli confirmed Peridot's threat when she warned the Crystal Gems that Peridot was leading a number of other Gems to Earth.
- In "Jail Break," Peridot was forced to flee the exploding Gem Warship in an Escape Pod, which was later revealed in "Joy Ride" to have crash-landed only a few miles outside of Beach City.
- Peridot took Steven's sticker from the Galaxy Warp and saved an image of it. She assumes this to be the logo of the Crystal Gems.
- Though very small, Peridot can be seen twice in "Joy Ride".
- According to Matt Burnett, Peridot might earn redemption in the future.

- The material the gemstone peridot is composed of, olivine, is often found in meteorites which may be a reference to Peridot being from space and falling to Earth in her Escape Pod.
- Peridot is the third Gem shown to fly.
- Peridot is the gem-quality olivine mineral. The mineral, olivine, is a silicate, and its crystal structure is made up of single isolated tetrahedron crystals. This tetrahedron shape has the same shape as Peridot's hair.
- Pure Peridot is rare, as it is unstable when released to Earth's environment.
- Olivine is often found in meteorites, though not exclusively.
- Peridot, along with sardonyx, is the birthstone of August. It is the planetary stone of Saturn.
- Peridot is one of the few gemstones available that can be found only in one color, although the shades of green may vary from light yellowish to dark brownish-green.
- Peridot is often associated with good luck, peace, and success. However, Peridot seems to have bad luck, failure, and violence with the Crystal Gems.
- An olivine's (and, by extension, Peridot's) chemical formula is (Mg, Fe)2SiO4, where the iron and magnesium combination gives it a light to olive green color. It's composed of:
- Forsterite (Mg2SiO4).
- Fayalite (Fe2SiO4).
|Peridot's gemstone is located in the center of her forehead. It appears to be smooth, without facets/rings.|
