Rubellite

Rubellite is a former Homeworld Gem that now resides on Earth with her lover Moonstone and their friends. Rubellite was once a bodyguard for Moonstone, who was a member of Blue Diamond's Court at the time, but fled Homeworld when she herself was threatened with being shattered for voluntarily fusing with Moonstone. The two would go on to join Rose Quartz's Gem Rebellion, ending up on Earth. Neither Rubellite or Moonstone were present when the Diamonds cast their Corrupting Light upon Earth.

Appearance
Rubellite is a Gem with very light red skin, dark red eyes hidden by her bangs, and like a lot of other soldier-type Gems has a build a bit more bulky than others, however is still slimmer than most soldiers due to not fighting for years. She has dark burgundy red hair that goes down to her waist, with her bangs covering her eye. She also has a red Rubellite gemstone in the palm of her right hand.

Rubellite wears a dark brown, bordering on black, sleeveless shirt with a collar and dark purple/maroon ribbon, alongside a skirt of the same colour as her shirt that goes down to her knees. She also wears dark purple/maroon shoes, with thigh-high stockings of the same colour.

Personality
Rubellite is an incredibly hot-headed, headstrong, and emotional individual, easily getting worked up over many things, no matter how small. This is best seen whenever she is in an Elementals ship. She makes her dislike of them very clear, even when they're meant to be acting casual for an escape plan, and will often berate and insult any member, even if it results in herself getting punished. In this sense, of all the other Gems, she is most similar to Kyanite. Rubellite has also been in a relationship with Moonstone for thousands of years, and the two are described as loving each other more than anything else in life. This is shown by their undying loyalty to each other, and how they both portray this in their own ways. For Rubellite, as she is extremely excitable, and has trouble not letting out all of her emotions and thoughts all at once, she does so by loudly exclaiming that she loves Moonstone, kissing her, and trying to spend as much time as possible with her lover. The two even sleep together, despite being Gems, and so not needing sleep. The two can even create a stable Fusion, known as Citrine. She is also extremely loyal to her friends, literally living with them, and has been shown to have a specific fondness for Scythia, Kyanite, and even the former Elemental Petalite, who Rubellite treats like a little sister, constantly teasing and flustering her, but also reminding her that she cares about her a lot.

There is a darker side to Rubellite too, however. As seen in the original Elementals Arc, Rubellite at the time held a huge grudge towards Petalite, not only as she was once an Elemental, but also because she aided them in trying to make Rubellite and her friends Elementals too, even berating their ways of life and ideals. This drove Rubellite to the edge, as she went on to partake in destroying Petalite's communicator after she had just fixed it, and took immense satisfaction in seeing the then Elemental come close to crying and sulking. Rubellite was later seen by Fuyuki messing with a piece of the communicator that she took, questioning why Petalite hadn't just left them all alone yet, and stating that they should have abandoned her in the forest they initially crash landed in earlier on, saying that Moonstone was an idiot for helping Petalite out of the tall tree they put her up in as Citrine, wishing she had instead fallen and shattered. Rubellite went on to attack and wound Fuyuki during a panic attack, before crying while saying that she was broken; that all she has ever been is a soldier built for war, and that still, after thousands of years, can't understand how Moonstone ever saw her differently, or loved her. From this, we see that Rubellite despises herself, believing herself to be nothing but a weapon, and that while she understands her flaws, she can't help but indulge in them, thinking of herself as weak minded, and saying that she doesn't deserve Moonstone. Rubellite also tells Fuyuki that she has never spoken to Moonstone about these kinds of things, as she fears that Moonstone will think of her differently, or, in her own words, "see me for what I really am". Rubellite promised to speak to Moonstone after, but never did, and so she still harbours these feelings of self-loathing for herself, while also still keeping them all to herself.

Background
There isn't much known about Rubellite's past, at least not in detail. She was once a Homeworld Gem and served as a bodyguard for Moonstone, who was a member of Blue Diamond's Court at the time. The two eventually developed feelings for each other, and began to Fuse in secret. At some unknown point in time they were caught, and so Rubellite was blamed, and was set to be shattered for her acts. The two instead ran from Homeworld however, and ended up on Earth. They went on to join Rose Quartz's Gem Rebellion, and would fight against Homeworld. The two were not present when the Diamonds cast their Corrupting Light on Earth, however, and so they were spared from becoming Corrupted. After the war, they both went on to simply live life on Earth. They would eventually cross paths with, and befriend, a young Fuyuki Chiba, and would make a deal with him so that they could live in the old shack that he and his friends Minori and Eisuka would sometimes go to so that they could play together.

Moonstone
Moonstone and Rubellite are in a romantic relationship, and both love each other to no end. They have been together for thousands of years, and so are rather inseparable, however, they are known to also verbally fight at times, especially when Rubellite is in a bad mood, as she becomes more confrontational to everyone around her. With Moonstone however, she usually ends up regretting what she says, and the two end up apologising. As such, while the two may be very different, and sometimes butt heads, they love each other, and don't like to be apart from each other for long.

Scythia
Scythia and Rubellite are both friends, and besides Pitou was the first other non-human along with Moonstone that Scythia met. They get along well, with Rubellite and Moonstone even Fusing into Citrine for Scythia, to which she exclaimed that they had become a "giant woman!". Rubellite is also shown to be rather protective of Scythia, shielding her when they were first on an Elementals ship.

Kyanite
Kyanite and Rubellite are both friends, who first met on the Elementals Spaceship 3X6, when they were both captured alongside others. Upon initially seeing Kyanite's fiery personality first hand, Rubellite even stated that she knew she was going to like Kyanite, which was met by a small bit of jealousy from Rubellite's girlfriend Moonstone. The two have been friends since then, and get along well, sharing quite a few similarities. They both are also known to treat their friend Petalite, who they both used to hate, as if she was their little sister, often both teasing and ganging up on her, much to her discomfort.

Petalite
At first, Rubellite and Petalite hated each other. With Petalite being an Elemental and Rubellite having taken part in the Gem Rebellion, the two had very different ideals and ways of life, and so clashed often. While Rubellite hated Petalite from the start due to her simply being an Elemental, Petalite did not seem to exactly hate Rubellite. Instead, she seemed to simply find her unpleasant due to her shouting and insulting her constantly from inside her cell. She only truly began to hate Rubellite when she and the others ended up getting Spaceship 3X6 blown up. In the future, they would clash often, with Rubellite going as far as to say she wished that she could just shatter Petalite and be done with it, although she never said this to Petalite's face. Now, however, they are on much better terms. With Petalite having spent more time with Rubellite and the others, she is much more loyal to them all now, even wanting to stay with them over being taken back into the Elementals. Rubellite herself has said that she knows Petalite "loves us really!" in the past, and has said herself that she loves Petalite too. This is more in a sisterly way, however, as Rubellite can easily be seen as treating Petalite like a little sister. Likewise, Rubellite is almost like an annoying older sister to Petalite now, as she often worries about her, yet at the same time enjoys teasing and flustering her.

Trivia

 * As stated in Homeworld's Game of Love, Rubellite Gems usually have a singular orange eye in the upper middle of their face, similarly to Sapphires, however, Rubellite's created in Era-1 are known to actually have two. While our Rubellite here has two eyes, and so is an Era-1 Gem, hers is dark red, not orange
