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

—Blue Diamond to Ruby, "The Answer"

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 once visited Earth after the Crystal Gems began their Rebellion, on an attempted diplomacy mission, as seen in "The Answer".

In her debut, she had displayed a significant 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 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 cut-out for her gemstone. She is also noticeably tall. This is clearly seen when her Pearl (who is the height of a tall human) is standing next to her: the Pearl only comes up to her knee, even when Blue Diamond is seated.

Relationships

Sapphire

The Answer 048

Sapphire telling Blue Diamond of the future events.

Sapphire was an aristocratic member of Blue Diamond's court. She was valued dearly for her ability to see into the future. She appears to talk frequently with her, by Sapphire's words. Blue Diamond went as far as to sentence Ruby to be shattered just for fusing with her, which resulted in Sapphire immediately fleeing the scene with Ruby and terminating her relationship with Blue Diamond.

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.

Ruby

To Blue Diamond, Ruby is nothing more than one of the common and insignificant soldiers under her command. When Ruby accidentally fuses with Sapphire, Blue Diamond immediately decides to shatter her gemstone as a punishment, even though the unexpected fusion saved Sapphire.

Peridot

Peridot was, at first, impressed with the murals of Blue Diamond and the other Diamonds in "It Could've Been Great". However, ever since the argument with Yellow Diamond in "Message Received", she became disenamored of the Great Diamond Authority in general.

Blue Diamond's Mural

  • Blue Diamond is the first of the Diamonds to be seen on-screen in an episode of Steven Universe.
    • However, Blue Diamond was not the first of the Diamonds to be revealed in Steven Universe media as a whole. Yellow Diamond was revealed in the extended theme song.
  • Blue Diamond's true voice is yet to be revealed. Her flashback debut was voiced by Garnet since she was telling the story.
  • Despite being a diamond like Yellow Diamond, the cut of her gem does not exactly match her yellow counterpart, in contrast to other gems of the same type, who appear to share color and cut. However, since the two episodes they appear in were storyboarded by different members of the crew, their gemstones may only look different due to the differing art styles of the crew members, as they appear to be of the same design – a rhombus-shaped decahedron with a rhombus facet and four rectangular facets on the sides.
  • Blue Diamond's importance is further emphasized, as she had her own palanquin with a curtain in the front and spider legs to move it around on its own. The Palanquin appears to have since been abandoned on Earth. ("Buddy's Book")
  • Rebecca Sugar has stated that blue colored gems are mainly diplomats.

Cultural References

  • Blue Diamond's appearance and her throne appear to be heavily influenced by Indian and Muslim culture. Her clothing resembles that of traditional Arab wedding dress, specifically a Henna dress.
  • 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.

Gemstone Information


  • Diamond is the official modern birthstone for April, and it is also used as an official sixty-year anniversary gemstone.
  • Diamonds are the stone of truth and victory.
    • It is associated with lightning and fearlessness, and for its properties of protection.
    • The diamond, in its rarity and beauty, is a symbol of purity and innocence, love, and fidelity, and embraces the strength of character, ethics, and faithfulness to oneself and others.
  • Diamond is the transparent, gemstone-quality crystalline form of carbon and it is indeed one of the hardest known natural substances on Earth.
    • Diamonds' hardness is the result of adamant chemical bonds between the carbon atoms.
    • There is no other gemstone in the same family as diamond, although there are a variety of very similar gemstones.
    • Diamond is pure carbon and is chemically the same as graphite.
  • Although traditional colorless or "white diamonds" are by far the most famous colored diamonds, yellow and brown diamonds are the most commonly occurring diamonds.
    • Other diamond colors include pink, red, orange, yellow, green, gray, and black.
    • Specific colors will trade under specific names.
      • Brown and yellow diamonds are often referred to as "champagne" or "cognac" diamonds.
  • If a diamond's impurities consist of boron and low level of nitrogen, the diamond will be a blue or gray color (Type IIb). Other blue diamonds are unrelated to boron; nickel or high concentrations of hydrogen are the likely causes of blue color in some diamonds.
  • The diamond is a p-type semiconductor.
  • Diamond deposits are found worldwide, the most notable being Africa, Australia, and India.
    • Approximately half of the world's diamonds come from Central and Southern Africa.
    • Canada has recently become a primary commercial source for fine white diamonds.
  • One of the most famous diamonds, the Hope Diamond, is a blue diamond, and is one of the largest diamonds ever to be cut and faceted. It is known notoriously for supposedly being cursed, depicted to bring forth misfortune to whoever attempts to wear it.
  • A notorious New Age scamming site, The Council of Love, utilises the blue diamond as a symbol of the Virgin Mary,[1] which may have inspired Blue Diamond's aesthetic similarities to the figure.
