Blue Diamond (Canon)

""How dare you fuse with a member of my court? You will be broken for this!""

"Blue Diamond" is a Homeworld Gem and a member of The Great Diamond Authority that rules over the Gem race. She makes her debut in "The Answer".

Description
She was once the supervisor of the colonization of Earth before abandoning it after the Crystal Gems' rebellion.

In her debut, she had displayed a great intolerance towards insubordination as she intended to break Ruby's gem, despite the latter fulfilling her duties and protecting Sapphire.

Appearance
Blue Diamond has a dark navy blue complexion. She has somewhat plump lips and a straight nose. Her gemstone is located on her chest. She wears a long, blue cloak of a slightly lighter shade and more vibrant than her skin, and a dark blue bodysuit with a cutout for her gemstone. She is also noticeably tall in height. This is clearly seen when her Pearl is standing next to her. Her mural portrayal from the Moon Base depicts her with long dark hair.

Sapphire
Sapphire was an aristocratic member of Blue Diamond's court. She was valued very highly because of her ability to see into the future, and Blue Diamond went as far as to sentence Ruby to be shattered just for fusing with her.

Blue Diamond's Pearl
Blue Diamond has her own Pearl, assumed to be her servant. Due to her brief and silent debut, not much is known about her, but because of her gestures, it can be assumed that this Pearl is fearful of Blue Diamond.

Ruby
To Blue Diamond, Ruby is nothing more than one of the common soldiers, insignificant to Blue Diamond. When Ruby accidentally fuses with Sapphire, Blue Diamond immediately decides to break her gem as a punishment.

Peridot
Peridot was at first impressed with Blue Diamond and the other Diamonds in "It Could've Been Great" but since the argument with Yellow Diamond in "Message Received", it's possible that Peridot is no longer fawning over Blue Diamond.

Cultural References

The frame of her throne has carved geometrical designs for windows, which are a common design in many Indian temples and houses.
 * The largest blue diamond, the Hope Diamond, also originates from India.
