|This article is about the Crystal Gem. You may be looking for another Ruby.|
That's what you think! I am an eternal flame, baby!
Ruby is a member of the Crystal Gems who was originally a Homeworld Gem soldier 5,750 years ago. After accidentally fusing with Sapphire, the two fled in order to prevent Ruby from being shattered at the hands of Blue Diamond. Ruby later joins the Crystal Gems. She made her official debut in "Jail Break". She is currently fused with Sapphire as Garnet.
Ruby has bright scarlet skin, burgundy irises and dark burgundy, square shaped hair. She is slightly taller than Steven and has a thick build. She wears a maroon and brown tank top and a matching maroon headband tied around her hair. Her ensemble also includes mid-thigh burgundy shorts, and short, pointed maroon boots similar to Amethyst's. Her gemstone is located in the palm of her left hand and has a square facet.
Before her and Sapphire's regenerations in "Jail Break", Ruby's top was black and maroon, and she still had her maroon headband and boots and brown shorts, as seen in "Three Gems and a Baby".
In "The Answer", which flashbacked to the Rebellion and when Ruby was still a soldier for Homeworld, Ruby's outfit was similar to her current one, except she had a maroon belt, she did not have a headband, and there was more brown than maroon on her tank top.
Approximately 5,750 years ago, Ruby lived on Homeworld as a common foot soldier.
Homeworld was attempting to create a new colony on Earth, which was overseen by Blue Diamond. She was part of the diplomatic team sent to stop Rose's Rebellion on Earth, as one of the three Rubies assigned to guard Sapphire, an aristocratic Gem with prophetic vision, adamant for destroying the uprising in its crib. When the rebels attacked, the three Rubies fought back, attempting to fulfill their jobs, only for two of them to be poofed by Rose Quartz and Pearl before turning to Sapphire.
Before her imminent poofing, Sapphire thanked Ruby for her service, at which point Ruby realized Sapphire had already predicted this and that she knew her physical form would be destroyed. Unable to accept that she had failed her mission of protecting her, Ruby tackled Sapphire to defend her from Pearl and caused them to accidentally form Garnet, changing the prophecy foretold by Sapphire. They immediately de-fused and were surrounded by an angry crowd. Furious that Ruby interfered with the outcome of the battle (and participating in an unsanctioned fusion with a member of her court), Blue Diamond ordered that she be shattered. However, Sapphire grabbed Ruby and jumped out of the Cloud Arena towards the Earth below, landing them softly with her levitation.
Ruby was distraught that she was unable to protect Sapphire. When it began to rain, she carried Sapphire to a cave for shelter, where she saw Sapphire's single eye for the first time. The two talked about their experience and feelings being fused as Garnet.
Ruby and Sapphire grew closer and eventually decided to fuse again. Garnet was found by Pearl and Rose shortly after forming. Upon being met with acceptance and not revulsion, she began to bombard Rose with questions about the events and circumstances that allowed her to become Garnet, as well as her own feelings about existing as a fusion. Rose told her to "never question this", and said that she was already the answer to all her questions—love. This would be the beginning of Ruby's existence as part of Garnet for the next few millennia, fighting the Gem Homeworld with the Crystal Gems to protect Earth.
Garnet is poofed by Jasper and as a result Ruby and Sapphire reform separately after being kept as prisoners on the Gem Warship with the other Gems.
Steven lets Ruby out of her cell and she immediately begins to look for Sapphire. Ruby only wants to find Sapphire and does not care about any other Gems on the ship like Lapis Lazuli. She listens to Sapphire's singing and heads in her direction. After Steven frees her, Ruby and Sapphire reunite in the center of the ship. They make sure they are both okay before fusing once more into Garnet.
Ruby and Sapphire converse while they are Garnet after they see the Cluster Gems. Ruby becomes enraged and Sapphire tries to calm her down. Garnet almost unfuses, but Ruby and Sapphire find peace once again.
Garnet unfuses because Ruby and Sapphire have a conflict over Pearl's deception in "Cry For Help". Ruby believes that Pearl tricking Garnet into forming Sardonyx is an unforgivable act, while Sapphire is more open to Pearl redeeming herself. Ruby storms out of the hotel room and paces outside to vent her frustration. Ruby's rage manifests in giving off intense heat (her rage burns the carpet and makes the pool temperature rise until it eventually evaporates, in contrast to Sapphires "freezing"). The next day, at The Best Diner in the World, Ruby angrily shakes their table. Sapphire says that she will cool down eventually, causing Ruby to summon her gauntlet and smash the table onto its side. Steven leaves the diner, upset, and Ruby and Sapphire follow him out to see what is wrong. After realizing the effect of their conflict has on Steven, they make up and re-fuse into Garnet.
A Ruby squadron arrives at the Barn, leading Garnet to unfuse so Ruby can get them to leave. Ruby nervously sneaks over and blends in with the other Rubies. She gets information by asking what the plan is. After finding out they are looking for the leader of the Earth mission, whom Ruby believes is Peridot, she tells the others that she will search the Barn. Ruby returns to the others, who are hiding in the barn, very anxiously. Sapphire calms her down and helps her out by suggesting she go back and telling the other Rubies that the Barn is a human home. Steven goes with Ruby to prove that the Barn is nothing but a human facility. Ruby tries to get them to leave once more, but Doc orders the Rubies to double check the Barn. Steven compromises by saying the Rubies can search the barn if they beat the "humans" in a game of baseball. During the game, Ruby pretends to be an unskilled player so the Rubies can lose, and she also flirts with Sapphire, causing the latter to lose focus. At the end of the game, Ruby encourages Sapphire until she finally hits the ball and wins the game for the Humans. Out of pure joy and pride, Garnet is accidentally formed, blowing the Crystal Gem's cover.
When Garnet is teaching Stevonnie how to stay fused under stress, Ruby is shown to get frustrated, but then have Sapphire comfort her, teaching Steven and Connie that they have to work together to stay together.
Fourteen years ago, Garnet de-fuses to show Steven, who she believes is a kind of fusion, how to unfuse, but Ruby and Sapphire re-fuse once baby Steven begins to cry due to missing Garnet.
Ruby goes along with Sapphire's plan to disguise themselves in order to enter Pink Diamond's Zoo undetected. Ruby pretends to be Sapphire's personal Ruby, and is the one that holds Steven's hands behind his back when the Gems pretend he is an offering for the zoo. Ruby claims that she left the gravity engine on the Roaming Eye so that the Gems have time to try and open up the zoo door without being noticed. When Holly Blue Agate leaves the area after talking about how great Blue Diamond is, Ruby becomes outraged because Blue Diamond rejected fusion, which is essentially her and Sapphire's love. When trying to open the zoo door, Ruby screams wildly, runs on the door itself (which leaves burn marks) and scratches the door.
Ruby continues travelling with Sapphire and Pearl after Steven is placed into the Zoo. Inside of the Rose Quartz Bubble Room, Ruby holds Sapphire's hand when she begins to freeze up in front of Blue Diamond. She fuses with Sapphire later on to stop Holly Blue Agate from harming Steven and Greg.
Ruby can't avoid the inevitable. She's just letting her emotions get out of hand.
|—Sapphire, "Keystone Motel"|
Ruby mainly embodies Garnet's strength and courage, while Sapphire embodies Garnet's cool nature and calm under pressure. Ruby is extremely passionate and emotional. She is known to have a short temper and violent ways of exhibiting her anger; this is best seen in "Keystone Motel", when she is infuriated to the point of using her thermokinesis and boiled the motel pool, even summoning her weapon at The Best Diner in the World. Despite her wild emotions, Ruby is still very willing to admit when she has taken her anger too far and will admit when she is in the wrong. She seems to put the welfare of Sapphire above all else, doing everything to find her and immediately made sure that Sapphire was well. When Garnet is extremely disturbed, Ruby also appears to show the most visible reaction in comparison to Sapphire. This is best demonstrated in "Keeping It Together" when Garnet's left eye began crying. After poofing the big Cluster prototype, Ruby and Sapphire start conversing with each other through their respective sides of Garnet, Ruby stating that the forced fusion experiments are Homeworld's retaliation against the Crystal Gems for their rebellion. While Sapphire shakily tries to calm themselves from this revelation, Ruby is clearly angered at the revelation of Homeworld's experiments and became hysterical. In "Gem Heist", Ruby shows animosity from the fact that Holly Blue Agate sees Blue Diamond as being merciful and starts to rant about its contradictions.
When not angry, Ruby is a suave romantic, soft with words, and quite flirtatious towards Sapphire. When she channels her emotion on love rather than on rage, she can be affectionate and extremely caring, feeling the need to protect, and even cool down for those whom she truly loves. These moments of calm also bring out the playful tease inside her, which is for the most part trapped under her wild emotions. Ruby also places much value in trust and fusion, being absolutely outraged with Pearl when she learns she was tricked into fusing into Sardonyx. She appears to be a bad conversationalist, occasionally speaking in somewhat unintelligible mumbles, a trait which she carries onto Garnet.
In "The Answer", it is seen that Ruby originally has very little sense of self-preservation or individuality, willing to take the blame for fusing with Sapphire and is content with her own inevitable destruction, arguing that there are "tons of her" in reference to the various identical Rubies found on Homeworld. She still possesses this to an extent as seen in "Jail Break" when she is only worried about Sapphire and said "Who cares?" when Sapphire asked if she is hurt.
In "Hit the Diamond", she is more calm and collected in terms of her anger than she had been in the past, but she seemed to get really nervous when she did not know what to do. She is also seen to be bad at lying under pressure, giving the Rubies the idea to search the barn. Her romantic nature is also on full display when she spends most of the game flirting with Sapphire to the point it affects the Crystal Gems' chances of winning. It is only when Steven talks to her that she focuses on the game and pushes Sapphire to do the same.
Like all other Era 1 Gems, Ruby can change shape, invoke a weapon, take refuge in her gemstone to heal, and adapt to any extraterrestrial environment's gravity. Ruby seems to possess greater strength than most Gems, as she was able to shake the walls of her prison with a single punch, lift Sapphire with little effort in "Jail Break", and flip a diner booth table with relative ease in "Keystone Motel". Like all Gems, Ruby can fuse with other Gems.
- When fused with Sapphire, they form Garnet.
- When fused with Sapphire and Amethyst, they form Sugilite.
- When fused with Sapphire and Pearl, they form Sardonyx.
- When fused with Sapphire, Pearl, and Amethyst, they form Alexandrite.
- When fused with other Rubies, they form a larger Ruby.
- Gauntlet Proficiency: Through sheer anger and feeling the need to release it through violence, Ruby can summon a gauntlet like Garnet's. Although only seen once, it is clear that Ruby possesses some knowledge of how to use it.
- Thermokinesis: Ruby can increase the temperature and generate heat. This is shown in "Keystone Motel" when her body gets so hot that it begins burning the carpet of the motel room, and when she boils the pool to nothing but steam in a very short amount of time. It is shown to be related to Ruby's emotional state, as the ability manifested itself when she got furious in the aforementioned episode and when she felt infatuated in "The Answer", as she set the grass beneath her ablaze when Sapphire thanked her. In "Hit the Diamond", another Ruby was so enraged at her team's potential loss that she set a baseball ablaze.
- Pyrokinetic Touch: This ability allows Ruby to set fire to whatever she touches depending on how angry she is. This is shown in "The Answer", where Ruby accidentally sets fire to the grass beneath her the minute she got flustered, and "Hit the Diamond" where another Ruby angrily throws a ball, setting it on fire.
- Heat Resistance: Ruby has not demonstrated this ability, but it was confirmed that the only reason Garnet can swim in lava is by Ruby.
- Enhanced Density: As seen in "Keystone Motel", Ruby can walk underwater.
Well you're here too, we're here together...
|—Sapphire, "The Answer"|
Ruby and Sapphire have a romantic relationship, shown in "Jail Break", when she immediately panics when realizing that the two have been separated and becomes reckless trying to find her, trying to pass through the energy field (as hinted by the screams of pain heard at the beginning), running around without checking if Peridot and Jasper are around and loudly shouting for Sapphire whenever she stops singing. When she finds Sapphire, the two embrace and Sapphire kisses away Ruby's tears, showing their romantic relationship. Ruby cares strongly for Sapphire's well-being, as she expressed deep concern for possible injury. Garnet's dialogue in "Love Letters" implies that Ruby and Sapphire's relationship developed gradually over a period of time. "Keystone Motel" reveals that their relationship can be strained at times due to Sapphire's precognition, causing her to be preoccupied with the outcome of events, instead of the events as they happen. This puts her at odds with the passionate Ruby, who very much lives "in the moment". In this episode, Ruby was furious over Pearl's deception in "Cry for Help", but Sapphire was not because she had seen that in the future they would all get along again. This greatly irritated Ruby, as she felt that Sapphire was acting cold, uncaring, emotionless and distant. By the end of the episode, she sees how much the ordeal affected Sapphire and, realizing that being furious is helping nobody, apologized for her behavior.
In "Hit the Diamond", the two unfused for a baseball game to protect Peridot. During the game, the two get distracted and start flirting, which causes them to almost lose. Steven tells the two to cut it out, which they begrudgingly do. When Sapphire states that all she wants to look at is Ruby, Ruby encourages Sapphire to focus on the ball, stating that she can look at her when she is running for home. When Sapphire gets a home run, she runs to hug Ruby and they accidentally fuse, despite being counter-intuitive to the plan of keeping Peridot and the Crystal Gems secret.
But I think they'd work it out if they'd just talk to each other!
|—Steven, "Keystone Motel"|
At first, Ruby seems distant towards Steven, only focusing on finding and forming Garnet with Sapphire as soon as possible. In reality, Ruby cares deeply for Steven, as hinted when she tries to tell him not to put his hand through the force field for his own safety, and cried along with Sapphire when they rescued Steven from suffocating in space in "Bubbled". Garnet also says that both Ruby and Sapphire already love Steven when he asks if he made a good first impression. She is also upset by the fact that their plan of revealing themselves on Steven's birthday had failed, apparent when she says to Steven, "Great! This is just perfect!" and "Don't look at me!" In "Keystone Motel", she obliges in Steven's attempts to calm her down, and upon seeing how Steven was affected by her and Sapphire fighting, Ruby and Sapphire both felt very guilty and made up. In "Hit the Diamond" when Steven tells Ruby to "stop being cute" to focus on the game, Ruby does so, showing she respects Steven enough to listen to him.
You met Ruby and Sapphire?!
|—Amethyst, "Jail Break"|
Pearl and Amethyst have been aware of Garnet's true identities for several millennia. Their perception of the two while separated remains unknown, but given their good relationship with Garnet, it can be assumed it is a positive one. Ruby holds a great deal of trust and respect for their teammates and becomes furious when Pearl betrays that trust in "Cry for Help".
This is punishment for the rebellion!
|—Garnet, "Keeping It Together"|
I don't feel like forgiving Pearl!
|—Garnet, "Keystone Motel"|
Not much is known about the relationship between Ruby and Pearl, except during "Keystone Motel", where Ruby feels used after Pearl tricked Garnet to fuse with her by rebuilding the Communication Hub twice. Ruby is very angry by this, which contrasted Sapphire's opinion of wanting to forgive Pearl, even leading to them unfusing. Apart from that, they appear to be on good terms.
Oh, boy... Where's the other one?
|—Greg, "Keystone Motel"|
Not much is known about her relationship with Greg, but Greg, at least, knew that she and Sapphire were the fusion components of Garnet, and considering most humans are not close enough to her to know this knowledge, this, at least, shows he knows her rather well.
Not much is known of Ruby's specific opinion on Lapis Lazuli, however, if it is anything like Garnet's, she is rather indifferent about her and would possibly look at her as not much of an ally, but not much of an enemy either. Upon meeting her in "Jail Break", she says, "Oh, it's just you...", implying that she holds more of a negative attitude towards Lapis Lazuli. However, Ruby's view of Lapis seems to have changed in Hit the Diamond, where they seem to be getting along, shown by Ruby offering Lapis a high five, which she accepts. This is probably because of her experiences of her through Garnet.
I can't believe all that stuff about Blue Diamond being merciful! She's a shatterer! She yelled at Sapphire! She hates fusion! And love!
|—Ruby, "Gem Heist"|
In "The Answer", Blue Diamond is outraged at Ruby and Sapphire for fusing. She states that Ruby will be "broken" before Sapphire runs off with Ruby. Her negative opinions on Blue Diamond are further confirmed in "Gem Heist" when Ruby struggles keeping her identity a secret due to Holly Blue Agate's compliments towards the "merciful" Blue Diamond. Ruby later on claims these compliments to be false, calling Blue Diamond a "shatterer", who yelled at Sapphire, and accusing her of hating fusion and love.

- Although she is not formally introduced until "Jail Break", her first appearance is in "Fusion Cuisine".
- When Alexandrite is separated, her silhouette, along with Sapphire's, is noticed. The left of "Garnet" is seen as Ruby, and the right of "Garnet" is seen as Sapphire.
- Garnet and the other Crystal Gems had planned to wait for Steven's birthday to introduce Ruby and Sapphire to him.
- When asked if Ruby is blind (after Ruby said "I can't see" in "Jail Break"), Joe Johnston merely stated that she was "used to being fused with Sapphire, and so, used to having two types of vision."
- Ruby possibly has her own room in the Crystal Temple, as the Temple Gate has a red gemstone and a blue gemstone that Garnet opens simultaneously.
- Most of Garnet's sensitive side seems to come from Ruby; whenever Garnet cries, her tears fall from her right eye (the red-colored one) that represents Ruby.
- Ruby cried when she and Sapphire met again in "Jail Break" while Sapphire herself appeared to remain calm in "Keeping It Together" after meeting the Cluster Gems.
- Ruby is the birthstone of Rebecca Sugar.
- During times of great conflict of opinion, she and Sapphire can talk to each other individually through Garnet, as shown in "Keeping It Together" and "Keystone Motel".
- The first hint of Ruby along with Sapphire was in the episode "Together Breakfast" when Garnet opens the door to her room. This shows two red and blue stones resembling gems light up creating an entrance for Garnet.
- In "We Are the Crystal Gems", Ruby is shown to be cracking or holding her knuckles, a sign of toughness, or that she is ready to fight while Sapphire is holding her hands together, interlocking her fingers.
- This shows that she is calm, graceful and passionate. On the other hand, Ruby seems calmer than expected from her, and Sapphire more upbeat than usual, possibly indicating that being Garnet brings balance to their personalities.
- Ruby is denser than water, and, as such, she sinks in the pool in "Keystone Motel".
- According to Peridot, this comes from gems' ability to manipulate gravity, making them able to float, and adapt to any planet's gravity.
- Ruby's thermoregulation of directly raising the temperature opposes Sapphire's thermoregulation of lowering the temperature, representing their polar opposite personalities.
- Ruby's ability to raise the temperature is somewhat of a pun, being that in "Keystone Motel", where Ruby is quite literally letting off steam, and acting like a "hothead". This is also shown when Sapphire says, "She'll eventually just burn herself out."
- Ruby and Sapphire's relationship is synonymous to the phrase, "fire and ice."
- Garnet's electrical manipulation stems from Ruby and Sapphire's combined abilities, as thunderstorms can result from the formation of masses of cold and warm air.
- Ruby (as well as any other Rubies) are in lower class of the Gems hierarchy as foot soldiers, although in reality, rubies are nearly as rare and valuable as a diamond, it most likely Ruby was mistaken with Spinel, a common gemstone found in large amounts in countries with hot weather.
- More proof of that is that actual rubies have a bright red or bloody pink colors, while spinels have a yellow-ish tone of red.
- Although Ruby's gemstone is in her left palm, she is shown summoning her gauntlet on her right hand.
- Ruby's gemstone cut is a square while Sapphire's is a triangle. While triangles are self-sustaining in that each side of a triangle supports the other two, squares are not (i.e. a free-formed square can be changed into a rhombus without stretching or contracting sides). This could be a metaphor for Ruby being the hotheaded counterpart to Sapphire, as she is shown to "collapse" easily as well.
- According to Garnet in "The Answer", Ruby and Sapphire met 5,750 years ago.
- Ruby's instrument has been confirmed to be "a crude waveform in between a square and a saw wave."
- In addition, her instrument was reverse-engineered from Garnet's as seen in "Keystone Motel".
- Ruby's gauntlet greatly resembles the anti-hero Hellboy's "Right Hand of Doom".
- Ruby and Sapphire's relationship is based on Ian Jones-Quartey and Rebecca Sugar's relationship.
- Currently, Ruby has the most known fusions out of all the Crystal Gems.
- "Hit the Diamond" marks Ruby's as well as Sapphire's first appearance outside of a StevenBomb.
- Ruby's design is a reference to Ian Jones-Quartey's character, KO.
- Rubies are composed of a material known as corundum, the second hardest crystal structure after diamond (9,10 on the Mohs Scale of Hardness).
- Since ruby is a member of the corundum group, it is closely related to sapphire and thus shares some properties with it, such as hardness, composition, and double refraction.
- In its pure form, corundum is colorless. The red color of rubies is due to chromium impurities.
- Rubies are the most expensive colored stone, going by karat.
- The word “ruby” comes from the Latin 'ruber' meaning red and, like many other gemstones, the ruby's symbolic meaning is heavily dependent on its coloring.
- Natural ruby is one of four "precious" gemstones (including diamond, emerald, and sapphire), known for its rarity, monetary value, and hardness (second only to diamond).
- Natural ruby can be distinguished from synthetic ruby by its inclusions; natural ruby typically exhibits inclusions, whereas synthetic ruby tends to be eye clean.
- The color of ruby is its most important quality factor. The most sought after color is a strong pure red to red with a hint of blue, called pigeon's blood.
- The vivid red color of ruby means that it is associated with desire, and it is thought by some to be a stone of love with an aphrodisiac effect.
- When the color of ruby is too light, it is classified as pink sapphire, but the line between pinkish-red ruby and pink sapphire varies by region.
- The ruby is closely associated with aspects such as vitality, life, passion, and fire, all of which can be symbolically linked to the color red.
- This shows in Ruby's emotional temperaments and overall emotional/angry attitude as well as her strength.
- It is said that rubies can over-stimulate people who are sensitive or irritable.
- Ruby is the traditional birthstone of those born in July and is also the zodiacal stone for Leo.
- Ruby is also used to celebrate the fifteenth and fortieth wedding anniversaries.
- The day assigned to Ruby is Tuesday (hence the Rolling Stones song, "Ruby Tuesday").
- The planet Mars is famously known as "the red planet", due to the high concentration of iron oxide (basically rust) on its surface. Rubies, along with all of the aspects mentioned above, have been linked with Mars in one form or another.
- Ruby is the national gemstone of Burma and Thailand.
|Ruby has a rich red stone in her left palm. It has a square facet, the front and back are symmetrical, and it has a light pink ring around it, which is usually hidden within her left hand, except when regenerating. It is a decahedron, specifically a truncated tetragonal dipyramid.|
