In the interactive page 1608 (Hoverboard) of the webcomic xkcd, the gems can be seen on a Warp Pad, along with a coin acting as a bubble inside a starship.
On April 12, 2016, Sony released a LittleBigPlanet costume pack which was based on the Crystal Gems.
Costume Pack which consists of Pearl, Amethyst, Garnet, Lion, and Steven.
At one point in the game Danganronpa v3: Killing Harmony, several of the characters are trapped in the same room and Tenko Chabashira, one of the people in the room, asks Himiko Yumeno, also trapped, if her face hurts and that her saliva can heal injuries and offers to spit on her face, probably referencing Steven's healing saliva.
The Cartoon Network show Craig of the Creek contains several references to Steven Universe. This is likely because the show's creators formerly worked on Steven Universe.
In the pilot, a Steven Universe doll is part of the pile of trash in the sewers.
In "Jessica Shorts", Guacola is one of the beverages in the refrigerator.
In "The Other Side: The Tournament", Steven Universe is mentioned by name and characters are shown to be fans of it. The King received Steven Universe boxing gloves as a present, and when the Creek Kids are looking at pictures of his gifts, a character sings the melody from "Stronger Than You".
In the Cartoon Network show OK K.O., every time a character gets "stars" in their eyes, the same sound effect that is played when Steven Universe characters get "stars" in their eyes is played.
The concepts of the characters P.K.O. and "T.K.O. and K.O. Combined" being fusions could be a loose reference to Steven Universe's concept of fusions. Similar to Malachite, K.O. and T.K.O. also have an internal realm where they interact with one another.
