Now the impurities you've encouraged in them are gone, now they are brilliant, now they are perfect, now they are... Me!
|—"Change Your Mind"|
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 had not left the Gem Homeworld in eons, and remained secluded inside her ship until she left Homeworld to help Steven heal the corrupted Gems. She made her debut in "Legs From Here to Homeworld".
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" and an official Hot Topic t-shirt, she has long black fingernails. Her gemstone is located on her forehead and is a side view of a round-cut diamond.
She wears a long translucent white dress that reaches the floor and is slit up both sides to her thighs, 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 (and possibly the brightness of her ship), her gemstone is barely visible, and only her eyes, nostrils, eyebrows, and mouth are visible because they're either black or have black outlines. A drawing by Rebecca Sugar, however, reveals the obscured details, as does the Hot Topic t-shirt.
But I'm not supposed to be like this. I'm supposed to know better. I'm supposed to BE better. I'm supposed to make EVERYTHING better.

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.
White also appears to have a soft spot for Pink. According to Blue, White used to join the rest of the Diamonds in Blue's Pool Chamber and would play games such as the Diamonds guessing what song Pink was singing underwater. Yellow also states that White never lets her or Blue into her ship, but she let in Steven, believing him to Pink. White endearingly gives Steven the nickname "Starlight".
According to Yellow Diamond, she never left her ship and never lets anyone in, except Steven/Pink Diamond, so it may be possible that she is a bit reclusive.
It is displayed in "Change Your Mind" that White Diamond is an arrogant perfectionist. She claims that Pink Diamond brings out the worst in other Gems, and that White herself makes them better by generously "removing their flaws." When White takes control of the Crystal Gems, she tells Steven that "there is nothing to hinder [her] white light sparkling through them," later saying that they are now "perfect". White Diamond has strict expectations on the way other Gems should behave, and this causes immense pressure that Yellow Diamond says could "crack a Gem." White takes this obsession so far that she breaks down after she becomes emotional, going as far as saying emotions are a flaw. This fact also reveals the biggest flaw in White, a control freak incapable of accepting something different and unique as well as being extreme close-minded outlook.
Nothing is known about White Diamond's exact past, but she believed she existed to "make everything better," and did so by imposing a strict system of hierarchies and castes upon the Homeworld empire. Her order persisted unchanged for many thousands of years. According to Blue Diamond, White was once closer to the other Diamonds, even taking part in games that Pink played with them. However, if Pink were to break one of Homeworld's rules, she would be locked away in a tower and White would always be furious with her. After Pink's alleged shattering on Earth, White grew distant from the others Diamonds to the point of never leaving her ship.
Around 4,500 Years Ago
When Pink Diamond was believed to have been shattered and Earth was no longer deemed to be a viable colony, White left Homeworld once that she participated in the Corrupting Light attack that corrupted every Gem on Earth exposed to the attack. After that, she returned to Homeworld and continue staying.
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 is 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.
White Diamond is not seen in "Familiar", but is mentioned several times. Steven relates to Pearl how he doesn't think she understands that he's not Pink Diamond, and later tells Yellow Diamond about his conversation with her, to which she remarks that it's incredible to he managed to get in even a few words to her, but laments that she never allows anyone else to see her in spite of Yellow's success as a conqueror. When Steven talks to Blue Diamond, she recalls an incident where Pink named a batch of Pyrite "Fool's Gold", which apparently infuriated White.
In Pink Diamond's room, Pearl tells Steven that Pink Diamond used to throw parties for all the Diamonds and their courts to attend, including White. This prompts Steven to don Pink Diamond's outfit and throw a ball for all of the Diamonds, where he plans to persuade White to help heal the corrupted Gems.
White appears once in the episode and is mentioned several times. She appears in Stevens dream, still in her ship and smiling at him. Blue Diamond says that since White might be coming to the Era-3 Ball, everything will have to be perfect. Steven hopes that White will come to the ball, but she does not show up. Instead, White Pearl takes her Diamond's place in observing the event.
When Steven and Connie try to escape Homeworld with the help of Blue and Yellow, White Diamond (speaking through White Pearl) tells them that they aren’t going anywhere. She then merges her ship with Pink’s. However, both Blue and Yellow Diamond’s ships, piloted by Bismuth, Lapis, and Peridot, attack her ship and manage to knock it over.
Later, Steven, Yellow, and Blue try to convince White to stop her ways and help everybody. White, however,ignores this completely, attacking both Blue and Yellow and turning them into mindless, obedient servants, like her Pearl. She transports Blue and Yellow inside her ship (which merged with hers) and attacks the Crystal Gems. She knocks them off the platform, and Steven drops Garnet, Amethyst, and Pearl’s gemstones. While falling, Steven manages to fuse with Amethyst, who then throws him over to Pearl. Steven and Pearl fuse and save Ruby and Sapphire. Steven and Garnet then fuse into Sunstone, but White stomps on them with the leg ship.
Sunstone lifts up the foot, however, and attacks the ships. White simply swats them away, and the gems decide they have to fuse into Obsidian. They fuse and attack White, along with Connie, Bismuth, Lapis, and Peridot. They all start destroying the ship, with Obsidian managing to slice off both of the ship’s hands. The Gems unfuse after being smashed against a pillar, and they enter White’s ship through its eye.
White asks what Steven is doing and asks if he wants his legs and his planet back. Steven asks what White did to the other Diamonds, but White shushes him. She says that both Yellow and Blue are imperfect due to their light, but she is perfect, due to her having every light in the spectrum. She then says that Pink is the part of her that she has to repress. She then suddenly attacks the Gems, turning Amethyst, Garnet, and Pearl into slaves like Blue and Yellow. White says that she removed their flaws, and that her white light is sparkling through them.
She states that they are brilliant and that the flaws Steven caused them to have are gone, and they are perfect like her. Steven tries to tell her that they are perfect the way they are, but White says that Pink likes to surround herself with inferior gems so she can be the best of the worst. Steven says that it isn’t true, and that even if it was, she’d be talking about his mom and not about Steven.
White laughs at this and says "your mom", but Connie arrives and White makes Pearl attack her. Steven tries to help but White makes Garnet and Amethyst grab him. Pearl disarms and grabs Connie. Steven tells her to let Connie go, but White says that it must feel good to surround himself with lower life forms, blaming everything on someone else. She says that that was why he became Rose in the first place, in order to deceive his friends.
Steven disagrees, saying that he isn’t Rose, but White points out that he knows things that he couldn’t possibly know if he wasn’t Pink. Steven says that he was just connecting with her, but White says that even though Pink took the form of Steven, her light is still shining through. She then picks Steven up, saying that it’s time to come out. She then removes his gemstone, which appears to reform, but whilst it shows the shapes of both Pink Diamond and Rose Quartz, ultimately the gemstone generates a holographic, seemingly emotionless Steven. When White questions where Pink is, the Gem Steven shouts "She's gone!" with such force that White is forced backwards, then walks back towards his human half, which is severely weakened. It appears that neither of the two Stevens is complete without the other one. White and the Gems under her control try to stop the reunion, but Gem Steven creates a featureless, multi-faceted shield which blocks all of White Diamonds' attacks, then "pops", creating a powerful shockwave which forces everyone back.
After Steven and the Gem Steven re-fuse, White Diamond angrily pounds her fists on the floor, stating that Steven should appear as Pink Diamond, that he is not half human, and that he is acting like a child. Steven retorts that he is a child, and asks what White's excuse is. Her and her slaves' cheeks turn pink, confusing White, and all the gems previously under her control return to normal.
Bismuth, Lapis, and Peridot arrive with the intent to fight White, but stop upon seeing the state that everyone is in. White asks herself what is happening, and she reaches out to Yellow and Blue. Both of them back away from her, saying that she is "off colored" after seeing her pink cheeks. White is startled, questioning if she is actually flawed.
Steven tells her to let people be who they are, and tells her that she can be what she wants to be. White says that she should know better, and that she should be better, and that she should make everything better. Steven says that she can, but she has to leave her own head. She then travels with Steven and the gems to Earth and witnesses the Off Colors arrive, and later helps cure all the Corrupted Gems. She then leaves Earth with Yellow and Blue, going back to Homeworld.
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. Since both Yellow and Blue Diamond showed fear of her, it could be concluded that she is much more powerful than the other diamonds are.
- 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.
- Mind Control: By zapping another Gem's gemstone with a white ray of light, White Diamond removes that Gem's color, replacing it with a complete whiteness which spreads out from the gemstone and controls the affected Gem. The ray can be blocked by Pink Diamond's Shield.
Gems under her control appear to gain access to White's powers, including the ability to form white bubbles for transportation, become intangible, levitate, and shoot White's controlling light from their eyes. A controlled Pearl was still able to draw her (also colorless) Gem Weapon to fight Connie, but it is unclear if this is the Gem's individual weapon or a facsimile.
Controlled Gems generally mimic White's movements, speech, and possibly state (a blush shown by White Diamond spread to all under her control), though she can also command them to perform specific actions or say certain things. Once released, Gems are disoriented and appear to have no memory of what happened or what they did whilst they were controlled.
A weakened emotional state may disrupt White's control; in "Change Your Mind", when Steven exposed a flaw in White Diamond, her control was undone when she realised this and blushed. It is unclear if this was a deliberate action on White's part, or an unconscious reaction.
White Diamond states that controlling other gems involves "shining her light through them" and that she does not want to "spread [herself] too thin", implying a possible limit to the number of gems she can control at any given time.
I've conquered so many worlds for the sake of the Empire. I do everything you ask and I do it all perfectly. But your very high standards put us all under a lot of pressure. A gem could crack under so much pressure. We Diamonds may be hard, but we are also brittle.
|—Yellow Diamond expresses her feelings to White Diamond "Change Your Mind"|
Both Blue and Yellow have, over time, grown depressed and heavily stressed by White's expectations of perfection. They described her as difficult and temperamental to Steven, and dreaded any kind of confrontation with her, though they were willing to stand together on "Pink Diamond's" behalf when they learned that she/Steven was still alive. Even when they decided White's order was unjust and had to be changed, it took Steven's encouragement for them to overcome that dread and speak their minds to White, expressing that they were sick of her standards and blaming them for the departure of Pink Diamond as well as the disappearance of their closeness to each other.
When White Diamond realized her own imperfection, Yellow and Blue were initially horrified by her loss of composure. Afterwards, as they healed the Corrupted Gems together, the two of them still appeared wary of her but willing to make up.
There you go again. Do you understand why you defend their flaws? I know why, Pink. You like surrounding yourself with inferior gems!
|—"Change Your Mind"|
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. "White Pearl" attends the Era 3 Ball in "Together Alone" in place of her Diamond, suggesting that White Diamond may use her pearl as her eyes and ears, later confirmed in "Change Your Mind". It was later revealed that White Diamond took away Pink Diamond's Pearl because of Pink's behavior. Afterwards, she took control of Pink Pearl, taking ownership of her in the process. As Pink Pearl is no longer under the control of White, it is unknown if she will remain being White Diamond's Pearl.
