Much like her in-series counterpart, Rainbow Quartz has a slender, curvaceous build, but with four arms instead of two. Her skin is warm pink in color, while her hair is bright yellow with light pink highlights, stylized in a messy bob. She has four eyes — with her top pair being periwinkle and her bottom pair being pink with visible pupils, a sloped nose with a pointed tip, and full, defined lips. Her gemstones are on her forehead and her upper left forearm, colored in shades of pink, purple, and yellow.
For attire, she wears a dark plum bra with a yellow star on the middle over a pastel pink leotard, plum-colored capris, and kitten heels of the same color with lighter plum toes. Additionally, she wears a transparent, loose-fitting light blue crop top, as well as a frilly mauve underskirt with a scalloped edge.
Nothing is known about Rainbow Quartz's personality yet.
Rainbow Quartz possessed standard Gem abilities, including bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability.

- Rainbow quartz is associated with hope and optimism.
- Quartz gemstones are very durable and hard.
