Sapphire

"Sapphire" is a Gem, and first appeared in "Jail Break". Currently, she is fused with Ruby.

Appearance
Sapphire has pale blue skin, and slightly lighter hair that covers her forehead and eye area. She wears a puffy, multicolored regal dress, with white gloves. Her lips and facial structure resemble Garnet's. She appears to have no feet, and there is an open geode underneath her dress that spans the entire length of the garment. Her gemstone is on the palm of her right hand, and has a triangular facet.

Abilities
Like all Gems, Sapphire can shape-shift, summon a weapon, and retreat to her gemstone to regenerate. Sapphire can fuse with Ruby to form Garnet.

Unique Abilites

 * Super Speed: Despite her long dress, she can travel at a high speed, an ability unmatched by any other Gems.

Personality
Not much is known about Sapphire's personality at this time, but it is very clear that she is very compassionate and level-headed. She seems to balence out Ruby's more impulsive personality when they're fused as Garnet.

Ruby
She and Ruby hold a romantic relationship, with Sapphire giving a kiss onto Ruby's face when they were reunited. This has also been confirmed by one of the storyboard artists, Joe Johnston.

Steven
She seems to know a lot more about Steven than Ruby, she also figured out Steven's human side makes him almost immune to the force field.

Crystal Gems
Pearl and Amethyst (Possibly Rose) knew Garnet was a fusion, meaning they have met Ruby and Sapphire when they were not fuse, and they don't seem have problems with them. Steven was the only one that didn't know about this. Originally, Garnet was planning to show him the truth later in his birthday.

Trivia

 * Sapphire is the birthstone of September.
 * She is known to sing, as displayed in "Jail Break".
 * With what's been shown of other fusions and their tendency to combine numbers of body parts (e.g. Opal's four arms and Sugilite's five eyes), it is possible that Sapphire has only one eye.
 * It's also possible Garnet is a more perfected fusion due to Ruby and Sapphire's relationship, having all her limbs fused and one pair of eyes to form her third purple eye.
 * This makes little sense as both Ruby and Saphire have 2 arms, yet Garnet ends up with "only" 2 as well. Furthermore, Saphire does appear to have legs, as depicted in artwork by the shows creator.
