White Diamond

"Hello, Starlight. You certainly gave everyone a scare."

White Diamond is a Homeworld Gem and the leader of the Great Diamond Authority that rules over the Gem race. She holds supreme authority over all Gems, including her fellow Diamonds, and is seen as a being beyond the rest of her kind. She has not left the Gem Homeworld in eons and remains secluded inside her ship. She made her debut in "Legs From Here to Homeworld".

Appearance
White Diamond has white spiky hair in a shape similar to a star pentagon and white skin. She is shown to be larger than her fellow Diamonds. Like the other Diamonds, she has diamond-shaped pupils, but hers are white instead of black, and she has large, full, black eyelashes. As shown in the flashback sequence in "Your Mother and Mine", she has claw-like fingers. Her gemstone is located on her forehead.

She wears a long white dress that reaches the floor and splits on the sides to expose her legs, shoulder pads, and a pair of intricately detailed dress sandals with high heels. She also wears a cape with black and gray stripes that is lined with glimmering diamond and star designs.

White Diamond is unique in that her body constantly radiates a bright light. Due to this, her facial features (aside from her eyes, nostrils, and mouth) and gemstone are not visible. A drawing by Rebecca Sugar, however, does show these obscured details.

Personality
Little is known about White Diamond's personality. She is described as being difficult, and that she has a temper that can take a while to cool down.

Upon meeting with Steven, she appeared both calm and understanding, yet curt and dismissive. She greets Steven (as Pink Diamond) warmly and with motherly affection, despite his appearance bearing no resemblance to how Pink Diamond actually looked. In addition, she treats the entire affair with the Earth, including the Rebellion, Pink's faked shattering, and her absence for the last 6,000 years with a mixture of patronization and nonchalance, remarking it all being simply one of "Pink's games" and asks Steven (as Pink) if he "had fun" and "got it out of [his] system." She interrupts Steven whenever he tries to speak to her, and then immediately sends him away to another room without warning as soon as she is done.

History
White Diamond has existed for eons. Her exact past is unknown, but she was able to rise to power and become the ruling leader of the entire Gem race. White is said to have not left Homeworld in eons.

White appears to have had a close relationship with Pink Diamond, as she calls Steven a nickname (Starlight) and is very aware of Pink's childish nature. When Pink Diamond was shattered and Earth was no longer deemed to be a viable colony, White participated in the Corrupting Light attack that corrupted any Gem on Earth exposed to the attack.

"Legs From Here to Homeworld"
Steven, the Crystal Gems, and the Diamonds travel to Homeworld to ask White for assistance in healing the Corrupted Gems. Before they even arrived at Homeworld, White appeared to already know that they were coming and that "Pink" was still alive because when they do reach the planet, Homeworld is cheering for the return of Pink Diamond.

White sends White Pearl to retrieve Steven, and when she does, White speaks to Steven as if he was Pink. White tells Steven that everyone is so relieved that Pink is alive and that she is relieved her little game is finally over. White then sends Steven to an unknown room.

Abilities
White Diamond possesses standard Gem abilities, but since she is a Diamond, her abilities are expected to be much greater than that of other Gems. It is implied, based on dialogue by both Yellow and Blue Diamond, that her power exceeds that of their own, with both showing fear at how she might react to the revelation that Pink Diamond was not actually shattered.

Unique Abilities

 * Aura Projection: The Diamonds can project an aura around them that they can control, they can either radiate it from their entire bodies or emit it from specific parts of their bodies, usually their hands. Not much has been shown of White nor her aura, but during the Diamonds' final attack against the Crystal Gems, White's aura was shown around her hand as a solid white corona-like flare around it.
 * Corruption Induction: Though the attack was meant to destroy the Crystal Gems, it corrupted every single remaining Gem on Earth.

Yellow & Blue Diamond
"We'll be lucky if she ever speaks to us again after this." Yellow and Blue Diamond appear to fear White Diamond, describing her as difficult and temperamental to Steven and wishing to avoid telling her about Pink's true fate. Yellow believes that if she were to speak to White on Steven's behalf, that her reaction would not be so severe. Ultimately, White denies both of them entrance into her ship.

Pink Diamond/Steven Universe
"As for this latest little game of yours, thank the stars it's over. Did you have fun? Did you get everything out of your system?" White Diamond appears to have had a relationship with Pink Diamond like that of a grandmother. Upon seeing Steven (who she, like the other Diamonds and Homeworld Gems, believes to simply be Pink), she calls to him endearingly with the nickname, "Starlight." Despite this, she does not take Pink seriously even more-so than the other Diamonds, brushing off her actions on Earth as if it were just a child's game.

White Pearl
Like all the Diamonds, White owns a personal Pearl. Little is known of their relationship. She is only seen acting as a messenger for White Diamond, escorts Steven to her, and then immediately leaves White's presence when she finishes her task.
