Six. Maybe more, if we meet the right Gem.
|—"Off Colors", on her number of component Gems|
Fluorite is the unaligned, voluntarily permanent fusion of six unknown Gems, making her debut in "Off Colors". Due to being a fusion between multiple Gem types, Fluorite was considered defective by Homeworld, resulting in her hiding with the Off Colors in the Abandoned Homeworld Kindergarten until she escaped the planet with the help of Lars. She then would travel through space onboard the Sun Incinerator with the rest of the Off Colors, before landing in Beach City in the episode, "Change Your Mind". She and the rest of the Off Colors resided on Earth, but after the events of "Little Graduation", she and the rest of the Off Colors have returned to space.
Because of her six Gems, Fluorite's appearance is not outwardly humanoid but instead, takes an appearance similar to that of a very large caterpillar.
Fluorite has a 6-segmented body (including her head) with each segment being seafoam green, earthy grayish natural blue, dark blue, indigo purple, then purplish pink, though the colors below her head may be a boat-necked section-colored bodysuit (still unclear). Each of her first two body segments has a pair of slender arms. The first of these arm pairs has elbow-length pale periwinkle gloves. Both arms are small-handed, and blue, although the lower pair seems more muscular. The other three body segments have short, thick legs with corresponding darker-colored boots. She has a total of six gemstones: two larger gems on her forehead, three on her first body segment (likely chest gems), and one on her second body segment (likely a navel gem). Her gemstones display moderately vibrant colors: earthy pink, lime-green, dark blue, light periwinkle blue, soft yellow and mixed-earthy purple, occasionally differing in coloration due to the lighting.
She has six interacting eyes, the top two pairs being teal, the bottom pair being lavender, (with the bottom pair often staying closed, creating the appearance of elderly wrinkles); another note regarding her eyes being that the top pair often behaves as eyebrows. She has a large, bulbous nose (which tapers softly up near her eyes) and wavy, near shoulder-length, fluffy pale turquoise hair with a variety of intermixed styles (due to her complexity) with no bangs, likely due to her forehead gems. She wears a pinkish-violet, bluish-purple, and dark blue wide-striped puffy vest that has 4 round sleeve-holes for her arms, and drapes loosely over her top two body segments.
Fluorite is a calm and wise Gem who is looked up to and respected by the other Off Colors. She often gives advice and speaks her mind, using her noticeably slow and deep voice. Fluorite also has a very open-minded attitude to fusion, as she has no problem with being a permanent fusion of six Gems and states that she would not mind adding even more if she meets "the right Gem". She's shown to be unwilling to leave Lars behind on Homeworld even if it meant going to Earth for a better life.
Her voice and facial features also make her somewhat appear like a wise, elderly grandmother. Fluorite's slow speech is due to having so many component Gems, which all have their own thoughts and opinions. They each need time to decide on what they will say together as Fluorite, thus resulting in slow speech.
At some point, the components that made up Fluorite decided to unite as one. Being a cross-Gem fusion, Fluorite was banished from Gem society. Fluorite and the other Off Colors have been living under Homeworld's surface in an abandoned Kindergarten for eons, hiding from Shattering Robonoids.
Fluorite greets Steven and Lars when they enter the abandoned Kindergarten. She explains to them that herself and the Off Colors aren't needed by Homeworld, which is why they remain in isolation. Fluorite tells the group that she is composed of six Gems, and could possibly expand if they meet the right Gem. When the Shattering Robonoids find their way into the Kindergarten, Fluorite is able to use her large body to circle around a wall, being undetected. After Lars sacrifices himself, Fluorite seems to not understand what death is.
Fluorite is happy to see Lars when he's brought back to life. When the Shattering Robonoids return, she tells the group to block the entrance. The robonoids leave once this is accomplished, with Fluorite telling the group that they have overlooked them for the time being. As the group makes a plan on what they should do next, Fluorite mentions that they'll be caught eventually as long as they stay in the Kindergarten.
Later, Fluorite believes that Lars will one day be poofed, and when he reforms, she says that whatever color Lars makes himself will be lovely. When Steven returns from Earth after traveling through Lars' head, he explains how great Earth is, she mentions that Earth was destroyed during the Diamond Attack. Steven tells the group that it wasn't and that on Earth, people can live freely, which Fluorite believes is wonderful. Lars later tells the group to go through his head to get back to Earth, even if it means leaving him behind, but Fluorite rejects the offer. She tells Lars that they won't leave him behind and that Off Colors stick together. Fluorite and the Off Colors then plan to travel with Lars around Homeworld to find an alternate route to Earth while Steven goes home.
Fluorite, along with the rest of the Off Colors and led by Lars Barriga, escape the Homeworld Kindergarten and go on the run. They steal Emerald's personal shuttle before crashing it on the planet Upsilon 9, travel to various planets, "impersonate imperial officers during a cosmic jubilee," and later sneak past 67 elite Citrine guards to steal Emerald's fastest ship (the Sun Incinerator) from a docking bay on the planet Klavius 7. While Emerald contacts them through the ship, Fluorite (now a 'chief engineer' under 'Captain Lars') checks on the engine. After Emerald threatens them, Fluorite tells Lars that the engines are all set, and Lars has the Rutile Twins pilot the ship into taking off in hyper-speed.
Fluorite and the Off Colors are still in space, attempting to return with Lars to Earth. When she first appears in the episode, she attempts to tell Lars that she has repaired a part of the ship, but because of her slow speech, Lars jumps to conclusions and causes the ship to lose power. Fluorite then retreats to the lower half of the ship again before meeting Garnet. Like the other Off Colors, she is offended and embarrassed by Garnet's statements. When Garnet mentions her affiliation with Rose Quartz, she is shocked, just as everyone else is, and claims that Garnet cannot be telling the truth, because Rose Quartz isn't real. She then listens in with the others as Garnet tells them the story of Rose Quartz. After the story, she finds herself inspired because of her representation of freedom, and along with the others, works to restart the core of the ship.
Fluorite, unlike the rest of the Off Colors, does not appear in this episode. However, it can be assumed she is still fulfilling her duty as the technical engineer, as the ship appears to be functional.
Fluorite and the rest of the Off Colors arrive on Earth but are shocked to see that the Diamonds are there. They are all eventually calmed by Steven, however. She is later seen having a conversation with Vidalia.
Fluorite serves as a background character along with the other Off Colors in the movie, appearing in several scenes with Lars. Fluorite also appears hanging out with Lars together at a table with Garnet, then later at the concert in the movie.
Fluorite presumably possesses standard Gem abilities and traits.
- Engineering/Technician Proficiency: Fluorite is capable of monitoring and maintaining the engine of the Sun Incinerator.
Fluorite initially seems curious about Steven by saying, "they don't look like Gems." After Steven tells her that he is half-human, she treats him like a normal Gem, explaining a few things to Steven about herself and the Off Colors.
Fluorite is friendly with Lars, stating after Lars is resurrected that "whatever color Lars chooses will be lovely." She did not want to leave Homeworld while leaving him behind. Like the other Off Colors, Fluorite comes to respect Lars for his actions that aided their escape from Homeworld and eventually regards him as her captain. Lars reciprocates the trust Fluorite has in him, working together efficiently as a crew aboard the Sun Incinerator.
Fluorite cares about Rhodonite, she is kind to her and doesn't seem to mind Rhodonite being impatient of her slow speech.
Not much is shown of the relationship between Fluorite and the Rutile twins, besides the fact that they have been around each other for a long time.
Padparadscha's relationship with Fluorite is very vague, as they haven't been seen interacting on a personal level.
Fluorite was introduced to Connie when Steven and Connie boarded the Sun Incinerator through Lars' head. Fluorite is very kind to Connie, regarding her as "another human friend".

- While her component Gems have not been revealed, Rebecca Sugar has stated the crew knows the Gems that make up Fluorite.
- Fluorite is the most complex fusion to appear, consisting of six component Gems. Despite being made with more Gems, she is smaller than Obsidian, a five-Gem fusion.
- It is uncertain what the facet of Fluorite's bottom forehead gemstone is, as it changes from a pentagon to a triangle to a rounded triangle to a circle throughout the events of "Off Colors" and "Lars' Head", and even to a diamond-shaped facet in "Lars of the Stars". This is most likely due to animation errors; stock poses and model sheet renders consistently depict it with a circle facet.
- In "Off Colors", it is hinted by Fluorite that she is a polyamorous relationship, something confirmed by Rebecca Sugar during a panel at San Diego Comic-Con in 2017.
- According to Rebecca Sugar, this idea was included at the request of kids at the Long Beach LGBT Center. 
- Fluorite has been confirmed to have a slow and expanding synth pad that plays every time she's on-screen.
| Fluorite's first unknown component's gemstone is located on her forehead. It is unfaceted and triangular in shape.
|Fluorite's second unknown component's gemstone is located on her forehead. Although animation inconsistencies lead to this gemstone changing cuts often, it can be seen in her model sheet that it has a circular facet.|
|Fluorite's third and fifth unknown components' gemstones are located on her chest. They are both unfaceted and triangular in shape.|
|Fluorite's fourth unknown component's gemstone is located on her chest. It is unfaceted and ovular in shape, similar to the gemstones of Pearls.|
|Fluorite's sixth unknown component's gemstone is located on her navel. It is a rhombus with a table cut, similar to the gemstone that powered the Obelisk.|
