Blue Diamond

Energy Construction: Once Blue Diamond broke free of Lapis water chains, she was able to create a ball of stellar light and it was able to shoot out blasts and explosions. Enhanced Strength: She is able to break Rose's sword with just the snap of her fingers and throw the barn off of her in a fit of rage. However, this might just be a simple matter of physics due to how large she is. Immense Durability: Blue Diamond seems to be more durable than other gems as she was able to survive when Lapis threw the barn on top of her and when her hand ship landed crashed on top of her and she came out without a scratch (while this would have likely poofed other gems). This is likely due to her sharing the same invulnerable nature as her gem, much as how Peridot's gem type gives her extreme durability. Clandestine Abilities White Capsule Generation: While controlled by White Diamond, Blue Diamond can create a kind of white capsule around itself or other gems, with several utilities. Levitational Transport: The capsule can also float around, as seen in "Change Your Mind". Teleportation: The capsule can also teleport Blue Diamond, as seen in "Change Your Mind". Levitation: While controlled by White Diamond, Blue Diamond has the ability to, indirectly, suspend her body. White Burst: While controlled by White Diamond (probably via the same), Blue Diamond is capable of shooting, through her eyes, a white energy beam equivalent to White Diamond's aura, in which it can also control, mentally, the affected gems.

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 is immune to Blue's first attack but collapses in tears on her next attempt. Gems who 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. It's unknown if this ability is limited to Blue Diamond's sadness or if she can project other emotions. Corruption Induction: Though the attack was meant to obliterate the Crystal Gems on Earth after Pink's supposed shattering, Blue, Yellow, and White Diamond's collective powers instead corrupted the remaining Gems on Earth. Corruption Reversal: Along with Pink/Steven, White, and Blue Diamond, Yellow Diamond has the ability to reverse the effects of the Corrupting Light on Gems However, it is implied that this is only temporary without the power of all four Diamond's. The four reversed the corruption on the water of Rose's Fountain in "Change Your Mind."
