Blue Diamond is an immensely tall, elegant matriarch from the Great Diamond Authority. She has light blue skin, long off-white hair that forms a loop over her chest, and droopy, sad eyes with diamond-shaped pupils. Her gemstone is located directly on her chest, and she usually wears a flowing, navy blue hooded robe.Appearance DescriptionPhysique: Towering and statuesque with wide shoulders and a thin, elongated frame.Face: Gaunt, with full lips, a straight nose, and prominent black markings under her eyes resembling heavy eyelashes.Attire: Draped in dark, navy blue, layered cloaks and cowls that function like a traditional mourning veil.PersonalityMelancholic & Nostalgic: Primarily characterized by her deep grief and perpetual mourning for Pink Diamond over thousands of years. She goes to great lengths to preserve Pink's memory, such as maintaining her "Human Zoo".Graceful & Merciful: In contrast to Yellow Diamond's harsh militarism, Blue is often portrayed as softer, occasionally offering mercy. She values justice, listens to cases (as seen in "The Trial"), and treats her court members with more grace.Prejudiced & Ruthless: Despite her sorrow, she can be fierce, judgmental of "lesser" gems, and completely intolerant of behaviors like fusion. For thousands of years, she was a harsh autocrat willing to cruelly punish or shatter rebels.Character Growth: Following the Steven Universe finale and Steven Universe Future, she overcomes much of her grief and actively uses her powers (like her aura and cloud-inducing tears) to spread joy and comfort to others.
