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 hopes that Yellow Diamond would send help. However, in "Catch and Release", Peridot claims that she has had no response from her.
