"Sapphire" is a Gem and a member of the Crystal Gems, who made her official debut in "Jail Break". She spends almost all of her screen time fused with Ruby as Garnet.
Sapphire has medium-blue skin and pale blue, wavy hair with bangs that cover the upper-half of her face. She lacks a nose and is slightly taller than Ruby. Her lips and facial structure resemble Garnet's. When her bangs are moved to the side, they reveal a single large eye with a light blue iris and a visible pupil in the center of her face.
Sapphire wears a floor-length dress. It features white, circular puffed sleeves, a navy blue top, and a blue skirt. Her dress has a sky-blue pinafore over the top. The skirt has several frilly layers in several shades of sky-blue which resemble an open geode. She also wears long elbow-length white evening gloves. While she has been officially confirmed to have legs, they so far have yet to be seen.
Personality
Sapphire appears to be very compassionate, sweet, and level-headed on top of having a lot of patience. She balances out Ruby's more impulsive personality when they're 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 Gem proof field almost immediately.
She can, however, come across as cold, distant, and even emotionless. This is because she possesses future vision and is able to see the resolution of events after they have happened; the present is not as important to her. However, this doesn't mean that she truly is emotionless and cold — when something affects her strongly enough in the present, she can become just as emotional, if not more-so, as her partner Ruby. Her blasé attitude to the present can make her appear somewhat passive-aggressive as well.
Abilities
Sapphire presumably possesses standard Gem abilities, such as weapon-summoning, bubbling, shape-shifting, fusion, regeneration, agelessness and superhuman strength/durability, though she hasn't been seen displaying any of them.
Future Vision: Sapphire is able to see the future to some extent. This was 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.
Sapphire's Thermo-regulation
Thermo-regulation: As shown in "Keystone Motel", Sapphire can drastically lower the temperature of her surroundings, even forming ice on the walls and freezing water. This ability contrasts to Ruby's ability to raise the temperature.
Levitation: As shown in "Keystone Motel", Sapphire is able to hover in the

air at will.
Super Speed: Sapphire seems to have a higher degree of speed than most Gems, possibly due to floating and not walking on legs.
Ruby: You know what's nice about being split up?
Sapphire: What?
Ruby: I get to look at you.

—Ruby and Sapphire, in "Keystone Motel"
Sapphire and Ruby have a romantic relationship. The first time they're seen together, she kisses Ruby, who's crying tears of relief after discovering she's safe. The rfrien nature of their relationship has been confirmed by both Joe Johnston and Ian Jones-Quartey. [1][2][3]
Garnet's dialogue in "Love Letters" reveals that their relationship developed over a period of time. 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 seems to be the more stable member of the relationship, who is aware of and used to Ruby's outbursts.
The episode "Keystone Motel" reveals that their relationship can be strained at times due to Sapphire's Future Vision causing her to be preoccupied with the outcome of events, instead of the events as they happen. This caused them some degree of conflict as Ruby showed to be very stubborn and unyielding. While Sapphire said that her anger was only "temporary", Ruby made sure to continue expressing her anger so as to not appear wrong. By the end of the episode, they were both brought to their senses by seeing Steven's concern and made up completely and immediately, showing that their fight wasn't a particularly serious one.
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 had already loved him. She can seem somewhat cold towards him when under stress, as she shot down his idea to talk thinks 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 Future Vision to see what channel he would like. After realizing that Steven felt like it was all his fault that Garnet and Pearl werefighting, Sapphire feels extremely guilty, showing that behind it all she truly cares about his happiness.
Pearl and Amethyst have been aware of Garnet being a fusion for at least several thousand years. Their perception of the two while separated remains unknown, but given their good relationship with Garnet, it can be assumed it's a positive one.
Upon encountering Hand Cluster, Sapphire and Ruby were both disturbed to the point of almost unfusing. While Ruby reacted with verbal anger and outrage at what Gem Homeworld had done to their fallen friends from the Gem War, Sapphire reacted more quietly, with deep sadness and tears. From their own comments, as well as that of Garnet herself, it can be assumed that they knew the individual members of that Cluster.
Before her introduction, she had a small cameo appearance in "Fusion Cuisine", when the Gems unfused from Alexandrite.
Sapphire is the only known Gem as to have a single eye (not counting the Centipeetle).
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's one eye could be a reference to Odin, the ruler of the Norse gods, who sacrificed one of his eyes for the ability to predict the future, or to the Greek mythological Cyclopes, who also did this.
She is known to sing, as displayed in "Jail Break".
The song that she sings from her jail cell has the same melody as "Stronger Than You".
This could mean that Sapphire had been planning to sing the song at some point, and it wasn't just made up on the spot by Garnet.
The song she sings is the shortest in the series, being only roughly 5 seconds.
Outside of close-ups, Sapphire is the second unfused Gem to be drawn with both a visible pupil and a visible iris, the first being Jasper.
The shape of Sapphire's legs can be seen in "Keystone Motel".
Sapphire does appear to have legs, as depicted in artwork by Rebecca Sugar.[4] 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.[5]
Sapphire, along with Ruby, does not have stars nor diamonds on their outfits.
Sapphire is the second Gem (after Rose Quartz) to wear a dress that obscures her legs.
During times of great conflict of opinion she and Ruby are able to 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 is one of three Gems to have made the most fusions (four) (Garnet, Sugilite, Alexandrite and Sardonyx).
Ruby and Pearl are the other two Gems to have made four fusions.
Sapphire's thermo-regulation of lowering the temperature directly opposes Ruby's thermo-regulation of 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), gives her "the cold shoulder", and acts cold and distant towards Ruby and Steven.
Sapphire is the first Gem seen to have some sort of floating or levitating ability.
Sapphire is also the only known non-fusion Gem that has her eye covered.
Sapphire, along with Peridot, is one of the few Gems who have not yet visually summoned their weapon.
Sapphire's gem cut is a triangle. Triangles are self-sustaining shapes in that each side of the triangle supports the other two. This can be a metaphor for her being the calmer counterpart to Ruby, whose gem cut is a square.
When Sapphire and Ruby are refusing, the background music is similar to that of Stronger Than You.
Sapphire is the birthstone for those who are born in September. As for the zodiac, it is regarded as the stone for Taurus and Virgo, as well as being a secondary birthstone for April.
Throughout history, sapphire has symbolized truth, sincerity and loyalty.
In times of antiquity and the Middle Ages, the term sapphire actually referred to lapis lazuli, but in the early 19th century, the description and definition of sapphire was 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.
While blue is the most traditional and classic color for sapphire, sapphire is actually found in a variety of different colors.
Sapphire colors are best viewed under natural daylight. In artificial or incandescent light, sapphire colors can appear darker and inky black-blue.
Sapphire colors are a result of trace impurities.
Colored sapphire (other than blue) is often referred to as fancy sapphire, and fancy sapphire is typically traded using color-specific names, such as yellow sapphire, green sapphire or purple sapphire.
Sapphire's gemstone is located on the palm of her right hand, featuring a triangular facet. As seen in "The Return"/"Jail Break", 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.
