After she accidentally fuses with one of her guards, Ruby, Sapphire flees the scene with her to prevent her from being shattered. When her bangs are moved to the side, they reveal a large eye with a dodger blue iris and visible pupil in the center of her face.

Sapphire wears a floor-length gown with white, rounded, puffy sleeves, a navy top, and a blue skirt. The skirt has several frilly layers in several shades of blue which resemble an open geode. Sapphire has feet that are usually hidden by her dress.

Rose told her to "never question this," and said that she was already the answer to all her questions—love.

This would be the beginning of Sapphire's existence as part of Garnet for the next thousand years, fighting Homeworld with the Crystal Gems to protect Earth.

Sapphire is very compassionate, fair and level-headed as well as patient.

She balances out Ruby's much more impulsive personality when they are fused as Garnet.

This first ever fusion of two different Gem types caused an uproar among the other Gems, during which Rose and Pearl escaped.

Blue Diamond was not pleased, and threatened to shatter Ruby for fusing with a member of her court and changing Sapphire's prophecy.

Sapphire's blasé attitude to the present can make her appear somewhat passive-aggressive as well.

But between Ruby and Sapphire, she is also shown to be more social, willing to start a conversation with Ruby about her thoughts about the Earth (shown in "The Answer").

Her gemstone is in the palm of her right hand and has a triangular facet.

Over 5,750 years ago, Sapphire lived on Homeworld, as an aristocratic Gem and part of Blue Diamond's court.

When in a confusing and distressing situation, she lets out more emotion contrasted to Ruby, as Garnet's left eye begins crying in the episode: "So Many Birthdays".
