I can see the path of fate as it stretches toward the horizon.
Sapphire has blue skin and pale blue, wavy hair with bangs that cover the top half of her face. She is slightly taller than Ruby. Her prominent lips and facial structure resemble Garnet's. When her bangs are moved to the side, they reveal a large eye with a sky-colored iris and visible pupil in the center of her face. She, along with Jasper, are the only Gems who lack a nose. However, she is the only Gem not to have anything replacing a nose.
Sapphire wears a floor-length gown with white, rounded, puffy sleeves, a navy top, and a blue skirt. Her dress has a blue pinafore over the top. The skirt has several frilly layers in several shades of blue which resemble an open geode. She also wears white elbow-length evening gloves. Sapphire has feet that are usually hidden by her dress. Her gemstone is in the palm of her right hand and has a triangular facet.
Over 5,750 years ago, Sapphire lived on Homeworld, as an aristocratic Gem and part of Blue Diamond's court. She was part of the diplomatic team sent to stop Rose's Rebellion on Earth, along with 3 Rubies assigned to guard her. Sapphire saw a future where the rebels Rose Quartz and Pearl were indeed caught and stopped; however, seven Gems, including herself, were going to be poofed in the process.
Just as she finished reporting her premonition to Blue Diamond, Rose Quartz and Pearl attack, as Sapphire predicted, and destroy the physical forms of six Gems, including two of her Ruby guards. However, before Sapphire was struck down, her remaining Ruby jumped forward and pushed her out of the way of Pearl's sword, accidentally fusing with her and forming Garnet for the first time. This first ever fusion of two different Gem types caused an uproar among the other Gems, during which Rose and Pearl escaped.
Blue Diamond was not pleased, and threatened to shatter Ruby for fusing with a member of her court and changing Sapphire's prophecy. However, Sapphire grabbed Ruby by the hand and ran off the edge of the Cloud Arena, floating down to Earth below. Sapphire was "frozen" because her future vision was wrong for the first time due to Ruby's impulsive nature. They found shelter in a cave, where Sapphire revealed her eye to Ruby and the two talked about their feelings when they were 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 Sapphire's existence as part of Garnet for the next thousand years, fighting Homeworld with the Crystal Gems to protect Earth.
Why does she always act like I'm being ridiculous? Just because she wants to pretend that she doesn't have any feelings!
|—Ruby, "Keystone Motel"|
Sapphire is very compassionate, fair and level-headed as well as patient. She balances out Ruby's much more impulsive personality when they are fused as Garnet. She is shown to be quick to understand a puzzle or situation, as she came to the conclusion of Steven's immunity to the energy field almost immediately.
Sapphire usually appears cold and distant to others, a trait that is sometimes reflected in Garnet. This is because she possesses precognition and can see the resolution of events before they have happened. As shown in "Keystone Motel", she just wants to do what she believes is right, which is to face problems by acting as though they have already been resolved, as she sees them in the future. Because of this, she has trouble letting out her emotions in the present, because she already sees the futures where these emotions have been resolved, opposite to Ruby, who lives in the moment and is more open about her emotions. Sapphire's blasé attitude to the present can make her appear somewhat passive-aggressive as well. But between Ruby and Sapphire, she is also shown to be more social, willing to start a conversation with Ruby about her thoughts about the earth (shown in "The Answer"). When in a confusing and distressing situation, she lets out more emotion contrasted to Ruby, as Garnet's left eye begins crying in the episode: "So Many Birthdays".
In "Hit the Diamond", she is shown to have a more violent side to her. When the leader of the Rubies threw the baseball hard, Sapphire managed to hit it by freezing the bat, while screaming with determination. She also shows a light, flirty side around Ruby that distracts her from the baseball game.
Sapphire possesses the standard abilities a Gem would normally have, such as, but not limited to, the ability to invoke a weapon, shapeshift, take refuge into her gemstone after being wounded to heal, and adapt to the gravity of any extraterrestrial environment.
- When fused with Ruby, they form Garnet.
- When fused with Ruby and Amethyst, they form Sugilite.
- When fused with Ruby and Pearl, they form Sardonyx.
- When fused with Ruby, Amethyst and Pearl, they form Alexandrite.
- Future Vision: Sapphire can see the future to some extent. This is hinted when she was able to find Ruby in a matter of seconds in "Jail Break", and then confirmed in "Keystone Motel". Unlike Garnet, she seems to be much more open with using this power; whereas Garnet only reveals future events to others when it is needed, Sapphire uses it to the point where she almost completely shuts out the events around her. According to Garnet, this ability is rare among Gems, enough so to place the rare Sapphire in Blue Diamond's court. Unlike Garnet's future vision, however, Sapphire appears to only see one future rather than multiple futures like Garnet can, such as when she could not see the future where Ruby saved her physical form from being destroyed (being poofed) by Pearl.
- Cryokinesis: Sapphire can drastically lower the temperature of her surroundings, even forming ice on the walls and freezing water. Sapphire is also able to freeze objects into solid ice, as seen in "Hit the Diamond" when Sapphire freezes a baseball bat. This ability contrasts to Ruby's ability to raise the temperature. When fused as Garnet, Sapphire's ice powers can fuse with Ruby's fire powers and form Garnet's electric powers.
- Levitation: Sapphire shows that she can hover in the air at will when she hovers onto the bed in "Keystone Motel" and when she can land herself and Ruby gently onto the ground in "The Answer".
- Enhanced Speed: Sapphire has proven to be able to travel great distances in a short time, possibly due to floating and not walking on legs, which is an ability that is not yet seen in any other Gem.
It's fusion, Steven! It's like Sapphire doesn't even care!
|—Ruby, "Keystone Motel"|
Sapphire and Ruby have a romantic relationship. The first time they are seen on the show, she kisses Ruby, who is crying tears of relief after discovering she is safe. The romantic nature of their relationship has been confirmed by both Joe Johnston and Ian Jones-Quartey.
Garnet's dialogue in "Love Letters" reveals that their relationship developed over a period of time.(In The Answer) In "Keystone Motel", because they were mad at Pearl for lying, they temporarily split up to calm down and come to terms with it. She is shown to be the calmer member of the relationship (as she said she was filled with rage but looked as calm as she was), sometimes to the point of seeming aloof, which infuriates Ruby further.
"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 caused them some degree of conflict throughout the episode, as Ruby was angry that Sapphire was so willing to forgive Pearl after manipulating them and that Sapphire seemed to dismiss her feelings. They share a great concern for Steven, which ultimately leads them to talk about and resolve their conflict at the end of the episode, and they form Garnet once more.
In "Hit the Diamond", they unfused to play baseball against the team of Rubies. Sapphire disguised as a human named Sophie, and Ruby posed as one of the rubies in the search squad. During the game, the two keep flirting, which causes them to almost lose the game. At the end of the game, Ruby encourages Sapphire enough to hit the ball. While running the home run, the two excitedly jump into each other's arms and accidentally fuse in front of the other Rubies, exposing their true identities in the process.
But we made him feel... like it was his fault.
Sapphire made less of an intent to hide her identity from Steven than Ruby, but still didn't tell him she was part of Garnet, as her and Ruby's intent was to properly introduce themselves to Steven on his birthday. She, along with Ruby, cares for Steven greatly, and when Steven asked if he made a good first impression, Garnet assured him that both Ruby and Sapphire already loved him. She even cried over him, along with Ruby, as they saved him from suffocating in space in "Bubbled". She can seem somewhat cold towards him when under stress, as she shot down his idea to talk things over with Ruby in "Keystone Motel" without even hearing him out. Despite this, she was still willing to watch TV with him, even using her precognition to see what channel he would like. After realizing that Steven felt like it was all his fault that Garnet and Pearl were fighting, Sapphire felt incredibly guilty.
Oh no! We were going to introduce you.
|—Pearl, "Jail Break"|
Pearl and Amethyst have been aware of Garnet being a fusion for at least several thousand years. Pearl first met Sapphire at the cloud arena when she was trying to attack Sapphire. However, due to Ruby interfering it caused them to fuse, and Pearl saw Garnet for the first time. Amethyst's relationship with Sapphire is unknown so far, but it can be assumed that it was a positive one.
It's not our fault!
|—"Keeping it Together"|
Sapphire and Ruby were both disturbed to the point of almost unfusing. While Ruby reacted with verbal anger and outrage at what Homeworld had done to their fallen friends, Sapphire reacted with deep sadness and guilt, due to her sense of responsibility for events that occur because she believes she could have seen them with her future vision. From their comments, it can be assumed that they knew the individual members of that particular Cluster.
My diamond, I have arrived.
Sapphire was once a subordinate of Blue Diamond, as well as an aristocrat in her court. Blue Diamond valued Sapphire highly due to her unique power to see into the future. After accidentally fusing with Ruby into Garnet, Sapphire rebelled against her superior to save Ruby and formally defected to the side of the Crystal Gems.

- "What Are Gems?" (gemstone only)
- "We are the Crystal Gems" (non-speaking cameo)
- "Fusion" (non-speaking cameo)
- Before her introduction, she had a small cameo appearance in "Fusion Cuisine", when the Gems unfused from Alexandrite, but she and Ruby quickly fused to keep their existence a secret until Steven's Birthday.
- Garnet's three eyes are a combination of one of Ruby's two eyes and Sapphire's one eye, with the third being mixed between the colors of both of their eyes.
- Sapphire does appear to have legs, as depicted in artwork by Rebecca Sugar and artwork by Hilary Florido . This is also indicated by the shape of Sapphire's dress when she goes down on her knees. Matt Burnett later confirmed this via Twitter.
- Sapphire's legs are revealed in "Hit the Diamond" while playing baseball as "Sophie", her human persona.
- Neither Sapphire nor Ruby have a star or a diamond on their outfits.
- However, when fused with Ruby, Garnet has a star on her chest.
- During times of great disharmony in opinion, she and Ruby can talk to each other individually through Garnet, as shown in "Keeping it Together" and "Keystone Motel".
- Sapphire and Ruby are both named after varieties of corundum (crystalline aluminum oxide, chemical formula Al2O3).
- In the extended theme song, Sapphire is gracefully holding her hands together, interlocking her fingers; this shows that she is calm, graceful and passionate while Ruby is shown to be cracking or holding her knuckles, a sign of toughness, or that she is ready to fight. On the other hand, Ruby seems calmer than expected from her, and Sapphire more upbeat than usual, indicating that being Garnet brings balance to both of their personalities.
- Sapphire's power is more of an emotional reaction rather than a conscious ability, as seen in "The Answer".
- Sapphire's cryokinesis - lowering the temperature directly opposes Ruby's pyrokinesis - raising the temperature, which could represent hers and Ruby's polar opposite reactions to stress.
- Sapphire's attitude in "Keystone Motel" could be a reference to her Thermo-Regulation powers, for instance, she "freezes Ruby out" (literally) and acts cold and distant towards Ruby and Steven.
- According to Garnet in "The Answer", Ruby and Sapphire met 5750 years ago.
- Out of all the Crystal Gems, Sapphire has personally engaged in combat the least. This may be because sapphires are made to be fancy, rich diplomatic court members.
- Sapphire's instrument has been confirmed to be "a gentle synth pad." 
- In addition, her instrument was reverse-engineered from Garnet's to be shown in "Keystone Motel."
- In "Keystone Motel" and "The Answer", Sapphire's philosophy towards future vision seems to be based around Hard Determinism, the idea that fate is always in control and that free-will is just an illusion. This is deeply in contrast to Garnet's philosophy of Soft Determinism, the idea that fate grants options in the exercise of free-will.
- According to Matt Burnett, Sapphire probably doesn't have a weapon.
- According to an interview with Rebecca Sugar, Sapphire didn't always have one eye in her pre-show development.
- Her and Ruby's relationship are based around Ian Jones-Quartey and Rebecca Sugar's relationship.
- Sapphire is the traditional birthstone of September and is the zodiacal sign of Virgo and Libra.
- Historically, it was the birthstone of April.
- Sapphire is the national gemstone for the United States and Greece.
- Throughout history, sapphire has symbolized truth, sincerity, and loyalty.
- In times of antiquity and the Middle Ages, the term sapphire referred to lapis lazuli, but in the early nineteenth century, the description and definition of sapphire were changed to the corundum variety we know today.
- Sapphire is typically very durable and considered to be one of the hardest materials on earth.
- It is the second hardest substance on earth after diamond, rating 9 on the Mohs scale of mineral hardness.
- Sapphire is a member of the corundum family and is closely related to ruby; the red to pink-red gem-quality variety of corundum.
- Most corundum is opaque to translucent and heavily included, suitable only for industrial use, including the production of abrasives used for sandpaper and machining of metal, plastics, and wood.
- Corundum itself is not a very rare mineral, but gem quality corundum is exceedingly rare.
- Since Ruby is a member of the corundum group, it is closely related to sapphire and thus shares some properties, such as hardness, composition, and double refraction, with sapphire.
- While blue is the most traditional and classic color for sapphire, sapphire is found in a variety of different colors.
- Sapphire colors are best viewed under natural daylight. In an artificial or incandescent light, sapphire colors can appear darker and inky black-blue.
- Sapphire colors are a result of trace impurities. Impurities for Blue Sapphire are Iron and Titanium.
- Sapphires that are not blue are often referred to as fancy sapphires. Fancy Sapphire is typically traded using color-specific names, such as yellow sapphire, green sapphire or purple sapphire.
- Some famous sapphires include the Rockefeller Sapphire, Burma Blue, and the Star of Asia.
|Sapphire's gemstone is located on the palm of her right hand, featuring a triangular facet. The front and back are symmetrical, and it has a light blue ring around it, which is usually hidden inside her body unless she's regenerating. It is an octahedron, specifically a truncated trigonal dipyramid.|
