|“||How dare you fuse with a member of my court? You will be broken for this!||„|
|~ Blue Diamond to Ruby|
"Blue Diamond" is one of the Four Diamonds that rule Home World, and is usually accompanied by her ward Blue Pearl. Like her fellow Diamonds, she is tall, intimidating and implied to be immensely powerful. She was the supervisor of the Earth Colonization project before the project was abandoned due to the Crystal Gems' rebellion, taking the demise of Pink Diamond hard as she secretly made regular visits to the site of her fellow Diamond's death. Blue Diamond is also the cause of Garnet joining the Crystal Gems, having condemned the fusion when first formed by accident.

Attack Potency: At least Multi-Continent level, likely higher (A combined attack from Steven, Garnet, Amethyst, Pearl, Bismuth, Peridot, Lapis Lazuli, and Lion did nothing but annoy her. Casually snapped Lapis Lazuli's water chains, which were durable enough to restrain Malachite. It's implied that the Diamonds are much more powerful by regular Gems by an unknown degree. Additionally, WoG implies that Diamonds have never been "poofed" before, which may imply that no known Gem has matched their might. Comparable to Yellow Diamond.)

Striking Strength: At least Multi-Continent Class, likely higher

Standard Equipment: Unknown (Gem Weapon which has not yet been revealed)
Intelligence: Should be high as she is the ruling Matriarch of Home World and oversaw the Earth Colonization project
Weaknesses: Emotionally sensitive, Sufficient damage to her physical form can revert her back to her vulnerable gem form which can be broken and destroyed. Her powers don’t seem to affect non-human animals (Lion was unaffected by her wave), while being less affective on something like a human (Connie wasn’t affected the first time, but the second time) or anything experiencing worse emotions than her (While being affected, it didn’t take much of a toll on Lapis)
- 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. Blue's aura is blue and has water-like properties. Though intangible, Blue was able to break Lapis' water chains from her hands upon coating her hands with her aura. She can use this as an offensive ability in both the physical and mental plane, as seen when she was able to focus her aura and attack Steven as he was projecting.
- 'Radiated Pathokinesis: Blue Diamond can engulf a large area with her aura which induces sorrow to anyone exposed to it. The induction is powerful enough to cause Gems exposed to the aura to break down and cry immediately unprovoked, even affecting Yellow Diamond to a small degree. When she unleashed her grief over Pink Diamond's death, she instantly rendered the Crystal Gems unable to fight. The aura is also potent enough to split all but the most stable Gem fusions that get caught in it apart, as Alexandrite came undone as soon as she was affected by the aura, while Garnet remained whole. The level of resistance to the ability varies. Non-human animals are apparently not affected, as demonstrated by Lion during Yellow and Blue's attack on Earth. Humans can still be affected as long as the aura is strong enough, as Connie was immune to Blue's first attack but collapsed in tears on her next attempt. Gems who feel that they have endured emotional trauma worse than the feelings induced by the aura can resist it almost completely, as Lapis Lazuli barely shed a tear upon being hit by the aura.
- Concussive Blast: Blue Diamond is able to concentrate her aura at a single point outside her body to launch long range energy blasts at her opponents.
- Energy Projection: She is shown to have some form of energy projection power that she uses for battle. The energy can be molded into different projectiles, from spheres to a hail of lasers, or combinations thereof.
