Moonstone bears an appearance similar to that of other Moonstones, as she is tall and skinny with a light profile. Her skin is light blue and she has four yellow and blue eyes with black pupils (two of which are on the back of her head and have blue sclera), a sloped nose, and full lips. Her hair is white and is medium-length, being shaved on the right side and having a long side bang. Her gemstones are on her chest and navel and are blue, yellow, and white.
She wears a sleeveless white, yellow, and blue dress, a yellow, blue, and light blue waistband, dark blue leggings with cutouts at the toes and heels, and loose yellow anklets. The skirt of her dress resembles a flower petal.
As a fusion, Moonstone is the embodiment of a selfless and deeply caring relationship, and is confident and happy just to be herself. She is everything good about them both, they bring out the best in each other. Moonstone is very confident in themselves and just really enjoys being together. Albite and Orthoclase's relationship is good but they got some mad personal and self-esteem issues.
She's basically a pacifist and avoids fighting whenever possible; she can defend herself but the only thing that would make her fight to stop herself from being shattered. She can be naive and too trusting sometimes.
It isn't common that Moonstone shows her mean, scary side, but she's definitely capable of it in the right situation.
KJD stated that Albite and Orthoclase as Moonstone would be a femme fatale and make everyone else flattered.
Moonstone possesses standard Gem abilities, bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability.

Once the Gems know that she isn't a threat they would get along pretty well, along with Garnet, they'd probably just chill. They wouldn't really talk a lot, but have more of an unspoken fusion comradery.
Lapis Lazuli and Peridot
Lapis and Peridot would probably both be a little iffy on Moonstone at first, but get used to her pretty quick. Because of Moonstone's telepathy she can tell if she's starting to annoy people and then react accordingly, and this would probably happen if she's talking too much around someone like Lapis Lazuli when she just wants quiet, so Moonstone would shut up, not because she's reading her mind but more just getting a general sense of increasing annoyance.
