Unknown Gems are Gems who have been visually shown through holograms, drawings, named, or other methods. They, or their gemstones, have not been officially identified.

"Steven the Sword Fighter"

"Sworn to the Sword"

"Keeping it Together"

"Historical Friction"

In Steven and Jamie's play, "Beach City or Bust", props for a Crystal Gem fusion and Corrupted Gem Monster can be seen. Not strongly resembling any other fusions, this is a fusion between some (or all) of the Crystal Gems. This fusion fights off a Corrupted Gem resembling both the Centipeetle Mother and the Big Bird.
