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.

Notable Attacks/Techniques:

Empathic Manipulation: During the trial, Blue Diamond was shown to be able to make those within the court room cry, even the likes of the stoic, strong Yellow Diamond. This could link to her being able to control other emotions depending on her mood. At an earlier point in the series, Steven would tear up just by being near Blue Diamond.
