Gooooood evening, everybody! This is the lovely Sardonyx, coming to you a-live from the soon-to-be former Communication Hub! How are y'all doin' tonight?

~ Sardonyx

Sardonyx is the main deuteragonist in the Cartoon Network series Steven Universe. she is a fusion form of Pearl and Garnet. She made her debut in "Cry for Help". She is also seen briefly in "Friend Ship".

She is voiced by Alexia Khadime. In the Japanese dub from the series, she is voiced by Megumi Toyoguchi.


Sardonyx is a very tall woman that has vermilion skin and pale peach/apricot-colored hair, that is styled into a tetrahedron with very rounded corners. Her torso and legs greatly resemble Garnet's but have less mass. As a fusion, she has four arms and inherits the same locations of her gemstones as her fused cooperators. She wears a black, tailcoat tuxedo-leotard with a tangerine bow tie and a small, black star on her chest. This tailcoat comes from Pearl's sash ribbon. The underside of the tail of her tailcoat is the same shade of tangerine as her bow tie. She wears two-toned, mauve-gray leggings under crimson tips surrounding the top part of her feet. On her first set of arms, she wears white gloves, exposing her hands except a white covering on her middle fingers like Garnet's. On her second set of arms, located on her abdomen, she wears white gloves that closely resemble Sapphire's gloves that extend to her elbows.

She wears round shades that resemble those of Alexandrite's, but are slightly transparent and tinted with a dark reddish-ginger-like color, which reveals that Sardonyx has four eyes, two on the bottom which are large and round, and two on the top which are thin, small, and narrow. Her top pair of eyes is magenta, while the bottom pair is crimson-colored. Sardonyx appears to have a small gap between her front teeth and plump lips. Her face is rather triangular, and her feet have small, bright pink diamonds on them.


Sardonyx, due to having a combination of Garnet and Pearl's personalities, acts theatrical but, at the same time, she can keep up an intelligent conversation. She usually has dramatic behavior, as shown as she talks to her friends like their her audience. She seems to have a great wit, as shown when she laughs at her own jokes. Also, Sardonyx acts rather snarky. This is shown when she remarks in a very pompous and comedic manner.

Sardonyx usually carries a cheerful attitude and thinks very highly of herself. She can be somewhat cocky at times. As a result of her cockiness, she occasionally forgetting about others' feelings. However, Sardonyx can be serious at times. For example, in "Friend Ship," when Garnet and Pearl fuse to escape a crushing deathtrap, she breaks out without hamming it up or sticking around any longer than necessary.

When she's pushed into battle, Sardonyx acts graceful and accurate. Yet powerful and rather playful, as shown as she messes with her opponents or audience with tricks and jokes. However, she is quite tactical and tries to make things perfect by thinking things up before acting.


Cry for Help

The Crystal Gems head to the Communication Hub, only to discover that Peridot has repaired the structure in an attempt to contact Yellow Diamond. Soon, Garnet decides to fuse with Pearl, forming Sardoynx. She cheerfully greets him while ignoring an annoyed Amethyst. Sardonyx soon forms her hammer and disables the hub. She unfuses after finishing. Later, the Crystal Gems observe Peridot's message being broadcasted again, and go back to the hub where Sardonyx continually dismantles the structure.

Friend Ship

During their pursuit of Peridot inside a derelict Gem spaceship, the Crystal Gems fall into a trap. Garnet and Pearl are confined in an enclosed pit which gradually contracts. They eventually fuse together, and Sardonyx drills out of the pit with her hammer, after which she unfuses.

Back to the Moon

On the Moon Base, Doc and her squad of Rubies fuse together to fight the Crystal Gems after discovering their deception. Steven opens the airlock on the base, pulling the fusion partially through the door. Garnet and Pearl quickly form Sardonyx, who smashes her hammer into the Ruby fusion, forcing her to unfuse. As the Rubies are sucked out into space, Sardonyx and Amethyst watch in horror as Eyeball drags Steven out with her.

Know Your Fusion

At the Beach House, Steven and Amethyst fuse into Smoky Quartz to show Garnet and Pearl. The two Crystal Gems are surprised and overjoyed. As Smoky begins to demonstrate their yo-yo tricks, destroying parts of the house in the process, Garnet and Pearl fuse into Sardonyx. She is excited to meet Smoky, and suggests that they need a bigger "stage" to get to know each other. She takes them to her room in the Crystal Temple, where she hosts her show, Sardonyx Tonight. At the start of the show, Sardonyx asks Smoky questions, hoping to learn more about them and their abilities. Smoky admits that they "ain't exactly a deck of cards," not having much to talk about other than their yo-yo. Determined to learn the full extent of their repertoire, Sardonyx begins the next part of her show during which she has Smoky perform a series of tests. Smoky is compared to the other fusions in their tests involving archery, strength, and fire breathing. Sardonyx is disappointed to see them perform poorly on all the tests, after which Smoky begins to disparage themself. As she observes Smoky's self-deprecation, Sardonyx realizes that she had ruined their initial plan to impress Garnet and Pearl. She unfuses in dismay, prompting the room to begin falling apart.


Steven Universe

Sardonyx, like the rest of the Crystal Gems, has a positive opinion of Steven, as she interacted with Steven frequently, is happy to meet him, embraces him, and calls him a "sweet little charmer." Sardonyx has shown that she is quite fond of Steven, telling him jokes and performing tricks. She even compares herself to the more destructive Sugilite to impress him even more. While doing this, she shows off her anatomy manipulation, precision with her weapon, and names of the qualities about herself that counter Sugilite's.


As a result to Amethyst disliking Sardonyx, Sardonyx usually ignores her. She that boasts that she has her better qualities around Amethyst, as shown in "Cry For Help".

Despite this, in "Know Your Fusion," Smoky Quartz doesn't seem to dislike Sardonyx, showing that Amethyst might have gotten over her dislike.

Smoky Quartz

Sardonyx first meets Smoky Quartz after Steven and Amethyst fuse to show Garnet and Pearl. Sardonyx takes them into her room in the temple where she hosts her late night talk show during which she interviews Smoky to learn more about them. She has them play games to try to find out what their special abilities are. This shows that, while she is interested in Smoky, she is very self-centered in her treatment of them, which causes Sardonyx to de-fuse when Pearl and Garnet realize how they were acting.


Sardonyx and Jasper have never met before, but, she mentioned her in "Know Your Fusion," where she calls her a trouble maker. This means that Sardonyx doesn't care about Jasper at all.


Sardonyx possesses standard Gem abilities and traits.


War Hammer Proficiency: Sardonyx can combine Garnet's gauntlets and put them on the end of Pearl's spear facing inwards to make a hammer. Her use of the war hammer is methodical in approach. She uses precise, keen strikes on specific areas to inflict the most damage while also reducing the amount of effort needed to take down a structure or opponent. She describes herself, and therefore her style of combat, as "specific, intelligent, accurate, faultless, elegant, controlled, surgical, graceful, and powerful!" (But yes, occasionally, she is known to smash).

  • Drill Transformation: By rapidly spinning the top part of her hammer, Sardonyx can transform her weapon into a drill that could easily break through the walls of the Ancient Gem Colony Ship that Garnet's gauntlets and Pearl's spear alone could not even dent.

Unique Abilities

  • Anatomy Manipulation: Sardonyx has been shown to have "doll joints", body segments that have full rotation independent of the rest of her body. During her initial attack on the rebuilt Communication Hub she was seen to spin her upper body above the sash while talking to Steven, her sash arms are seen moving separately from the rest of her body throughout the scene, and during the final strike her whole body is spinning on one joint while her feet remain pointed up and immobile. In "Back to the Moon", it is shown that not only can her waist spin in this fashion, but also her neck. She is able to swing her body around without taking her eyes off the Ruby fusion. In "Know Your Fusion", Sardonyx was able to move through the cramped space of the house and through the Temple Gate with minimal difficulty.
  • Enhanced Calculations: Sardonyx could knock out the correct pillars to make sure the hub did not collapse until she wanted it to. She may have inherited this from Garnet, who mentions her ability to sense structural integrity in the episode "Cheeseburger Backpack". Or this could have come from Sapphire's future vision; she may have been able to see if knocking down a certain pillar may have caused the entire hub to collapse. She may have also inherited this from Pearl, who is precise and accurate.
    • As with Garnet, it is currently unknown whether this is a Gem ability/power that is inherited from Ruby/Sapphire unique to both Garnet and Sardonyx or a simple observation.
  • Due to being a Pearl fusion it is unknown if Sardonyx is acrobatic. A hint of her having this skill is when Amethyst is singing "Tower of Mistakes" Sardonyx is shown doing back flips while destroying the tower.


That's a nice yo-yo, but I want to know the yo-you.
~ Sardoynx to Smoky Quartz in "Know Your Fusion"
Always running 'round Kindergartens and causing trouble! Boy, that didn't quite work out for her. Guess she should go back to preschool, am I right, folks?
~ Sardoynx talking about Jasper in "Know Your Fusion"
Hm... 'smash' is the word one would use to describe what... someone else might do.
~ Sardoynx to Steven in "Cry for Help"
Oh my stars! If it isn't Steven Universe, we finally meet! So what do you think? Was I worth the wait?
~ Sardoynx meeting Steven in "Cry For Help"
What's this? An encore performance? Just couldn't get enough of me, could you?
~ Sardoynx in "Cry for Help"




  • Sardonyx's outfit unusually features both diamonds and stars, with pink diamonds on her shoes, and a black star on her chest. The pink diamond design on her shoes also appears on Pearl's outfit in "Space Race", though in the middle of her torso, and indicates her former service to Pink Diamond.
  • Sardonyx asks Steven if she is "worth the wait," referencing to how long she took to appear in the show.
  • According to Matt Burnett, Garnet and Pearl fused into Sardonyx with a hand-based dance in "Friend Ship". This supports the fact that fusion dances may vary depending on the situation, the time they have, and how the Gems are feeling.
  • Her top set of eyes functions as eyebrows, similar to Malachite.
  • Sardonyx can be formed if Ruby and Sapphire are not Garnet.
  • Sardonyx doesn't include any Quartz-type gem despite being named a Quartz.
    • This is also the case with Rainbow Quartz.
  • Sardonyx's eyes occasionally glow a brighter orange when she is talking to Steven, telling jokes, or when summoning her weapon. It is unknown if this is from lighting, a mistake in animation, or if they naturally brighten when she gets excited.
  • According to Joe Johnston, he added a gap between Sardonyx's teeth because he also has a slight gap in his.
  • Her war hammer is made with the gauntlets facing inward, yet the design has them facing outward.
  • According to Aivi Tran and Surasshu, Sardonyx's theme song shows the influence of Garnet and Pearl's respective music on each other (and as such, their personalities as well).
  • Garnet's presence has influenced Pearl's piano to become confident and bombastic, while Pearl's presence has influenced Garnet's bass and synth sounds to become theatrical and jazzy.
  • Rebecca Sugar hopes for Sardonyx to have a musical number in the show.
  • Her comical personality, coupled by her gloating of her own qualities around Amethyst, might be inspired by the word "sardonic", meaning "disdainfully or ironically humorous".
  • As shown in "Know Your Fusion", she shows evidence of being aware of the 4th wall, referencing directly Cartoon Network, merchandising being necessary for her show to be on air, and Sugilite's voice actress being paid for her voice being featured despite not actually being in the episode nor recording any new lines.
  • Smoky Quartz used the phrase "You're like twenty feet tall!" When describing Sardonyx's size, which is commonly used as figure of speech when describing tall beings.
  • Her showman-like personality is in many ways similar to Ruby Rhod, Chris Tucker's character in The Fifth Element.
  • Her face bears a striking resemblance to Spongebob SquarePants from the popular animated television series of the same name.
