This is an interpretation of a realistic Yellow Diamond in the eyes of Peridot right when the quote: "You are out of align..." is said, with dazzling eyes and long neck.

This Homeworld Gem Leader intimidated everyone by her size and authority demanding Earth's Destruction.

Yellow Diamond is a Homeworld Gem and a member of the Great Diamond Authority that rules over the Gem race. She was first shown in the extended theme song and made her official debut in "Message Received".

She is now Scapolite, the Axis between lifes. As the first Agin-Councilor of all the Gems, she dresses herself with a dark and catholic dress, assuming brownish colors in the shadows, the only gem trusted with the power of contradiction. Devil's Advocate, no more decisions would be made without her last word, capable of changing everyone opinions by legitimate means. Scapolite is the anti malfeasance. 

 "Malachite" is the fusion of Jasper and Lapis Lazuli, who first appeared in the episode "Jail Break". She is currently held at the bottom of the ocean, at an unknown location. Malachite is a massive fusion, nearly equal in size to Sugilite. She possesses six arms, of which the lower four function as legs. She has four eyes with light-teal irises and pointed teeth. Her first set of eyes function as eyebrows. Her eyes change shape based upon who is controlling her, with her eyes being small and catlike when Jasper controls her and larger, round when Lapis controls her.
