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 in future episodes. She was first mentioned by Jasper in "The Return", and by Peridot in "Cry for Help" and "Catch and Release". She is not simply another Homeworld gem, but most likely a high ranking official part of the Diamond Authority. (Fans believe that the Diamond Authority consists of Yellow, White and Blue diamond.)

Appearance
Yellow Diamond appears to have a slender build and pale dove yellow skin. She has large, yellow irises and black pupils. Her height may be the same as Jasper's, if not taller. Her hair is a deep yellow and styled into what appears to be a bob-cut with two spiked tips. She seems to have a pointed, upturned nose and plump lips. She has large, pointed shoulders. Her outfit has the same diamond shaped top of her shirt, as most Homeworld gems seem to have. Her pants/skirt is cropped out, but is shown to be a slightly darker shade of gold than her hair.

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

Yellow Diamond seems to hold some sort of authority over Jasper and Peridot, as they needed to report to her. Her symbol of authority is seen in their uniforms, which feature a yellow, diamond-shaped symbol. This trend tends to consist with all Homeworld Gems with the exception of Lapis Lazuli.

In "The Return", Lapis Lazuli and Peridot appear to fear her.

In "Cry for Help", Peridot sends out a distress signal using the Communication Hub in hopes that Yellow Diamond would send help.

In "We Are the Crystal Gems", a silhouette of Yellow Diamond can be seen alongside Jasper, Peridot, and Lapis Lazuli.

In "Catch and Release", Peridot frantically claims that she had "no response from Yellow Diamond".
