Moonstone

Moonstone is a former Homeworld Gem that now resides on Earth with her lover Rubellite and their friends. Moonstone was once a part of Blue Diamond's Court, but fled the Homeworld when Rubellite was threatened with being shattered, due to the two of them voluntarily Fusing. The two went on to eventually end up on Earth and join Rose Quartz's Gem Rebellion. The two weren't present when the Diamonds cast their Corrupting Light on Earth, and so have remained as they were since then.

Appearance
Moonstone is a Gem with light baby blue skin, azure blue eyes and rather long messy white hair that reaches down to near her mid-back, and has a small ahoge. Moonstone has a more mature, human build than most Gems, similarly to the Gem Rose Quartz, but not on the same level.

Moonstone wears a dark-blue sleeveless sweater with a high, rather loose turtleneck collar. There is a diamond shaped hole in the sweater at her chest, showing her white and light blue Moonstone gemstone in, and just under that is another larger white diamond, running down from the middle of the hole to near her waist. She wears a skirt of the same colour, which makes the sweater and skirt almost look like one long dress. She also has a white pair of shoes with thigh-high stockings of the same colour.

Personality
Despite the two being in a relationship together, Moonstone could be seen as a polar opposite of Rubellite in terms of personality. Unlike her girlfriend, Moonstone is a lot more calm and relaxed, finding it better to talk their way out of problems or, if they have to, at the very least sneak out of bad situations, instead of just taking everything head-on. As such, during the times that they've been captured by the Elementals, Moonstone has been one of the Gems that have tried to come up with a minimum risk, minimum harm to others plan to escape, while Rubellite stresses and shouts at every Gem that passes their cells. She is shown to be much more intelligent than Rubellite too, being able to strategise when needed, and understand where people are coming from, even if said people may see Moonstone as an 'enemy'.

Her love for Rubellite is one of the few things that kept Moonstone going when they were alone on Earth for hundreds of years, with no humans or other Gems in sight to keep them company. Unlike Rubellite, however, Moonstone shows her love for her girlfriend in much more subtle ways, not feeling as if she needs to shout it out for the whole world to hear, but instead just enjoying being with her, and missing her for almost all of the time that they're apart from each other. Because of this, while Moonstone has no problems with Fusing into their Fusion Citrine with Rubellite, she prefers to instead stay unfused for as long as possible, preferring to be right next to her, allowing her to embrace and be with her in person, instead of combined into one.

Moonstone has been seen to dislike violence too, and is always the one to try and split up any fights, physical or verbal, that Rubellite may get herself into. On top of this, a flaw of Moonstone's is how trusting she can be. In fact, she is often too trusting of people, usually taking their word as the truth without too much fact-checking, which often ends up getting her in trouble. While she has gotten better about it over the years, she still has trouble dealing with it, as she hates confrontation of any kind and avoids it at all costs, even when it puts herself or others at risk. As such, Moonstone is sometimes seen by others as being "too weak to do what needs to be done", and is sometimes left out of plans because of this.

Background
There isn't much known about Moonstone's past, at least not in detail. She was once a Homeworld Gem and served as a member of Blue Diamond's Court, being an aristocratic Gem. Here, she would meet her girlfriend Rubllite, who was created to be a guard for Moonstone. Overtime, 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, being seen as a lesser Gem than Moonstone in Homeworld's caste system, 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.

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

Petalite
Petalite and Moonstone are both friends, with Moonstone being one of the first people out of the gurls to actually give Petalite a chance to settle in and change. Moonstone is also one of the only people that know how Petalite truly feels about Copal, as she opened up to Moonstone after some pushing, with Moonstone saying that talking about her feelings may help, and that it'll also help her to settle in faster. Moonstone is seen to care about Petalite's well-being too, offering to hold her hand when she was worried about going into the Elemental ship that they were brought to by Ametrine, who was disguised as Amy at the time. Moonstone seems to take Petalite's concers and opinions more seriously than the others too, also seen when they went to Ametrine's ship, which Petalite seems appreciative of.
