Prime, prime, prime. You Amethysts are so cliquey.
|—"That Will Be All"|
Jasper, nicknamed Skinny, is a Homeworld Gem who briefly appeared in "That Will Be All". A defective Quartz soldier from the Beta Kindergarten, she is tall and skinny instead of muscular and bulky like most Quartzes. She is a subordinate of Blue Diamond and commanded by Holly Blue Agate. 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".
Skinny has moderately light orange skin with scarlet markings. Her eyes are yellow with black pupils, has feathery black eyebrows, and resembles her perfect "sister" Jasper in this manner. Unlike the other members of the Famethyst, her top does not cover her entire torso, fitting her like a short tank top, leaving the majority of her torso bare.
Her blue uniform has a Blue Diamond insignia.
Like the Crystal Gems' Amethyst, Skinny has an easygoing personality. Skinny has a sharp and sarcastic sense of humor, joking that the Amethysts are "cliquey" and constantly talk about the Prime Kindergarten. with the other members of the Famethyst. Skinny dislikes her commander Holly Blue Agate, who frequently abuses the Quartzes both physically and mentally (disdainfully referring to Skinny and Carnelian as "hideous off-color Betas"). Because of their distaste for Holly Blue Agate, Skinny 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, Skinny mocks her and disobeys her orders to attack the Crystal Gems.
Skinny 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. Skinny jokes that the Amethysts are "cliquey" and constantly talk about the Prime Kindergarten. When Amethyst asks where Carnelian is, Skinny says that she’s off celebrating no longer being the shortest.
Later, the Crystal Gems escape but are stopped by Holly Blue Agate. When Holly Blue is being humiliated, Skinny mocks her and disobeys her orders to attack the Crystal Gems. Skinny waves goodbye happily as the Crystal Gems are able to escape.
Skinny makes a cameo appearance alongside the Famethyst during Amethyst's part of "Happily Ever After".
Skinny presumably possesses standard Gem abilities.
Skinny is a member of the group of Quartz guards nicknamed the "Famethyst". Both defective Gems from the Beta Kindergarten, Skinny seems to have an especially close friendship with Carnelian. Unlike other Homeworld Gems, the other Quartzes are kind to defective Gems like Skinny and Carnelian.
Skinny jokes that the Amethysts are "cliquey" and constantly talk about the Prime Kindergarten. When Amethyst asks where Carnelian is, Skinny says that she’s off celebrating no longer being the shortest.
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! That's right, Blue is back already!
|—Holly Blue Agate, "That Will Be All"|
Skinny 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. Skinny and Amethyst are both defective Quartzes.
Skinny and the Famethyst are quite friendly to the Crystal Gems, happily waving goodbye after helping them escape Homeworld. Also being pictured together in Steven Universe: The Movie, it can be assumed that the Crystal Gems and Skinny have met since the events of "That Will Be All" and remain on good terms.

- A Quartz whose Beta Kindergarten hole is malformed and described as "skinny" is briefly alluded to by Amethyst in "Beta", presumably referencing this defective Jasper.
|Skinny's gemstone is located on her navel. It is orange and yellow, and it is circular in shape. It resembles a cabochon, a gemstone that has been polished, but not faceted.|
