I'm not the shortest anymore!
|—"That Will Be All"|
Carnelian is a Homeworld Gem who briefly appeared in "That Will Be All". A defective Quartz soldier from the Beta Kindergarten, she is a subordinate of Blue Diamond and commanded by Holly Blue Agate. She, like the Crystal Gems' Amethyst, is smaller than she should be (albeit slightly taller than Amethyst). She is employed at Pink Diamond's Zoo as a guard, and she is a member of the group of friendly Quartz guards known as the "Famethyst".
Carnelian has bright scarlet skin, darkish-maroon hair, and peachy-orange eyes. She also possesses spaced, crowded teeth uncharacteristic of any other gem. Another notable trait is her catlike lips, just like the Crystal Gems' Amethyst, whom she boasts a slight height advantage over.
Her blue uniform has a Blue Diamond insignia.
Like the Crystal Gem Amethyst, Carnelian shares a happy-go-lucky and humorous personality with the other members of the Famethyst. Carnelian is quite energetic, quick to pick up Amethyst in celebration upon no longer being "the shortest anymore".
Carnelian dislikes her commander Holly Blue Agate, who frequently abuses the Quartzes both physically and mentally (disdainfully referring to Carnelian and Skinny Jasper as "hideous off-color Betas"). Because of their distaste for Holly Blue Agate, Carnelian and the other Quartzes assist in helping Steven and Greg escape from the Zoo. When Holly Blue Agate is being humiliated by the Crystal Gems, Carnelian mocks her and disobeys her orders to attack the Crystal Gems.
Carnelian was created on Earth in the Beta Kindergarten during the Gem Homeworld's control of the planet. She was presumably created for Pink Diamond (like the other Quartzes created on Earth), but after Pink Diamond was allegedly shattered, they were reassigned to Blue Diamond and sent to Pink Diamond's Zoo in order to maintain and protect the facility, under Holly Blue Agate's command.
The Crystal Gems' Amethyst meets many other Homeworld Quartzes (whom she refers to collectively as "the Famethyst"). These Amethysts inform her of her serial number being Facet-5 Cut-8XM. Among the Amethysts and Jaspers are two defective Gems: "Skinny", a tall and skinny Jasper, and Carnelian, shorter than most Quartz. Carnelian happily and energetically boasts no longer being "the shortest anymore", quickly picking up Amethyst in celebration.
Later, the Crystal Gems escape but are stopped by Holly Blue Agate. When Holly Blue is being humiliated, Carnelian mocks her and disobeys her orders to attack the Crystal Gems. Carnelian waves goodbye happily as the Crystal Gems are able to escape.
Carnelian presumably possesses standard Gem abilities.
Carnelian is a member of the group of Quartz guards nicknamed the "Famethyst". Both defective Gems from the Beta Kindergarten, Carnelian seems to have an especially close friendship with "Skinny" Jasper. Unlike other Homeworld Gems, the other Quartzes are kind to defective Gems like Carnelian and Skinny.
What are you all doing in here?! Get to your stations! Even you hideous off-color Betas! Get out of your cubbies and into your places! It's the least you can do for the Diamond that kept you worthless, sorry Gems in service!

Carnelian and the members of the "Famethyst" quickly become friends with Amethyst, who they consider part of their group. All made on Earth, the Quartzes have a playful, 'sisterly' relationship with Amethyst. Carnelian and Amethyst are both defective Gems, coming out of their exit holes shorter than most Quartzes. Carnelian happily and energetically boasts no longer being "the shortest anymore", quickly picking up Amethyst in celebration.
Carnelian and the "Famethyst" are quite friendly to the Crystal Gems, happily waving goodbye after helping them escape Homeworld.

- A defective "Carnelian" who came out of her Beta Kindergarten hole sideways was briefly alluded to by Peridot in "Beta", presumably referencing this defective Carnelian.
- Along with Lapis Lazuli, Bismuth, Holly Blue Agate, Emerald, and Watermelon Tourmaline, she is the sole individual of her Gemstone seen (although a Gem resembling Lapis is seen in "The Answer").
|Carnelian's gemstone is located on her left shoulder. It is a circular orange-red gemstone with a hexagonal facet, and seems to be a slightly larger gemstone than that of her peers — this size difference may be related to her defect or simply illusory due to her shorter stature. A third possibility is that her gemstone is meant to be the size it is, being as this is the only carnelian seen so far.|
