Yellow Diamond

"Forget about the mission! Yellow Diamond needs to see this... thing."

"Yellow Diamond" is a Homeworld Gem who is yet to be revealed. She is mentioned in "The Return", "Cry for Help", and "Catch and Release".

Appearance
Not much is known about Yellow Diamond's appearance, since she has only been seen from behind in the extended intro, but she has yellow skin, eyes, and hair. Apparently, she has a pointed, upturned nose and plump lips. Her hair is a short bob with two spiked tips. She has black eyebrows as well. Her shoulders are large and pointed. She looks tall and slender and wears a black and olive outfit very similar to Garnet's bodysuit. It is not known where Yellow Diamond's gem is placed or how it looks.

Jasper/Peridot
"This is Peridot, transmitting on all frequencies from abandoned crystal system colony planet Earth, to Yellow Diamond. My mission has been compromised, my escort and informant are gone, and I am now stranded! Please send help!"

Yellow Diamond appears to be their superior, as they work for and report to her. In "The Return", when Jasper mentioned Yellow Diamond, not only Lapis Lazuli winced, but Peridot showed fear as well. A silhouette of Yellow Diamond can also be seen alongside Jasper and Peridot in "We Are the Crystal Gems".

In "Cry for Help", Peridot sends out a distress signal using the Communication Hub in the hope's that Yellow Diamond would send help. However, in "Catch and Release", Peridot claims that she has had no response from her.
