Blue Pearl

"I thought I heard someone. I think we're not alone."

Blue Pearl is a Homeworld Gem that belongs to Blue Diamond. She first appeared in a flashback in "The Answer" and made her official debut in "Steven's Dream".

Appearance
Her height and physical frame are identical to the Crystal Gems' Pearl and Yellow Pearl; she is altogether very lean, with long legs and arms, and has a tall oval-shaped head with a prominent and pointed nose. She has sky blue skin and chin-length, messy, periwinkle hair. The upper portion of her face is covered by her bangs, similar to how her owner Blue Diamond covers her face with her hood. Her outfit consists of a periwinkle bodysuit with an open diamond-shaped keyhole neckline, similar to Yellow Pearl's, a knee-length, frost blue, sheer skirt, and pale blue flats. Her gemstone, a powder-blue pearl, is on her chest and it is a round polished cabochon.

Personality
Blue Pearl is a shy and quiet Gem, performing her duties without speaking. The only instances where Blue Pearl speaks is when Blue Diamond talks to her first. Blue Pearl is also seen to be easily frightened, as shown when Greg Universe pops out of the bushes before her; she gasps and has a fearful expression on her face. Like other Homeworld Gems, Blue Pearl is shown to not have a problem taking on requests by Blue Diamond.

"The Answer"
Blue Pearl stands on Blue Diamond's Palanquin, and silently watches Sapphire speak with Blue Diamond.

"Steven's Dream"
Blue Pearl bows with Blue Diamond at Pink Diamond's Palanquin. She hears Steven Universe and Greg Universe moving in the bushes behind them, so she checks out the area, informing her Diamond that she believes they're not alone. Blue Pearl jumps a little when Greg appears before her suddenly, and she tells her Diamond that she has found a native. After being asked to, Blue Pearl escorts Greg to Blue Diamond. She follows her Diamond onto her ship as they head into space with Greg.

"That Will Be All"
Blue Diamond and Blue Pearl return to Pink Diamond's Zoo where the former continues to mourn for the late Pink Diamond. The two are promptly joined by Yellow Diamond and her Pearl. After failing to persuade Blue Diamond to shatter the remaining Rose Quartz Gems and cease her grieving, Yellow Diamond commands her Pearl to sing for Blue Diamond to comfort her. Yellow and Blue Pearl begin to sing a song in which they act as backing vocalists for Yellow Diamond, who persists in trying to convince her fellow Diamond to move on from their loss.

"The Trial"
Blue Pearl acts as the court illustrator at "Rose Quartz's" trial, crafting illustrations of the proceedings and reconstructions of Pink Diamond's shattering as told by Steven. During the proceedings, she is briefly affected by Blue Diamond's pathokinesis wave, and later is shocked by the defending Zircon's allegations, particularly in the question regarding Pink Diamond's Pearl.

Abilities
Blue Pearl possesses standard Gem abilities.

Blue Diamond
"Yellow Pearl: All rise for the luminous Yellow Diamond! Blue Pearl: And the lustrous Blue Diamond." For millennia, Blue Pearl has been traveling around with Blue Diamond. She respects her Diamond, constantly bowing in her presence and saluting her. Blue Pearl follows every command Blue Diamond gives her (though not as enthusiastically as Yellow Pearl), and doesn't appear to have any issue with that. In "The Trial", she arrived in the tribunal announcing her as "lustrous", serving as a signal of her respect for her Diamond.

Yellow Pearl
The bulk of their relationship has not been explored. In "That Will Be All", when Yellow Pearl stands next to her, she smirked at Blue Pearl with pride, whom grimaced in return. Afterwards, when ordered by Yellow Diamond, they sang together but only after Yellow Pearl implored her to join in. In "The Trial", Yellow Pearl gave her a worried look after Zircon mentioned Pink Diamond's Pearl.

Pearl
As with Yellow Pearl, their relationship is unknown, but they are seen standing together in a flashback in "Now We're Only Falling Apart". Also, in "The Trial", when the defending Zircon mentioned Pearl, both Blue and Yellow Pearl appear shocked.

Trivia
