Sapphire

Sapphire is a character from Steven Universe.

She is voiced by Erica Luttrell.

Sapphire is a Crystal Gem and a fusee to Ruby, forming Garnet. She represents Garnet's kindness, compassion, and level-headedness, while Ruby represents Garnet's courage, strength, and impulsivness.

She was shown to hold some intelligence, as she came to the conclusion that Steven was immune to the force field due to his half-human side almost instantly.

Order of the Just
Both Sapphire and Ruby are members of the Order by default as they both are halves of Garnet. However, they were also members before fusing.
