Blue Diamond

Blue Diamond's History

Blue Diamond, or Blue for short, is a Homeworld Gem and a member of the Great Diamond Authority that formerly ruled over the Gem race. She first appears in a flashback in "The Answer" and debuts in person in "Steven's Dream".

As a result of Era 3, Blue Diamond now uses her powers to bring joy to other Gems through her clouds, created from her vaporized tears, which make someone happy once coming into contact with them.

Ancient History

Not much is known about Blue Diamond's exact past. Over the course of thousands of years, Blue Diamond amassed a great amount of respect, colonies, and Gems. Her role in the Great Diamond Authority was one of diplomacy, meaning she enforced White Diamond's rules on Homeworld.

When Pink Diamond was eventually created, Blue and the other Diamonds grew a close relationship with her. Blue found Pink's immature personality to be charming at times, but would also tend to be strict on her under specific circumstances. In "Familiar", Blue recalls a time where Pink named a batch of Pyrite "Fool's Gold" to White's dismay. She also recalls the many times her, Yellow, and White would gather at her pool area, where Pink would sing underneath the water while they would attempt to guess the song. Blue, along with the other Diamonds, would also attend the many parties Pink would hold in celebration of the Diamond Authority's achievements.

Whenever Pink was locked in the tower as punishment, Blue would come to reprimand her for her wrongdoing. One such incident involved Pink bringing colorful organic creatures into the ballroom, only for them to run loose through the palace and chase the Pearls around. One of the creatures had crawled up Blue's neck, making her shriek and swat it away. An exasperated Blue added that White was displeased to the point that she would likely take Pink's Pearl away.
