Carnelian

Carnelian is a defective Quartz soldier from the Beta Kindergarten who briefly appeared in "That Will Be All". She, like

the Crystal Gems' Amethyst, is smaller than she should be (albeit slightly taller than Amethyst).

She has a circular orange-red gemstone with a hexagonal facet. Her gemstone is located on her left shoulder, and seems to possess a slightly larger gemstone than 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 gem of her type seen so far.

She 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 Crystal Gem Amethyst, whom she boasts a slight height advantage over.

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. However, this is more vague than Skinny's exit-hole connection, as much of the Beta Kindergarten was orange and red.
