Sapphire

"Sapphire" is a Gem who will appear in "Jail Break". She was first and only seen in a preview of the episode. Not much is known about her.

Appearance
She has very light blue hair, slightly lighter skin than Lapis Lazuli, and a puffy, regal dress with white gloves.

Abilities
All Gems can shape-shift, summon a weapon, and retreat to their gemstone to heal.

Garnet
It is theorized that Sapphire, along with Ruby, may be the two halves of Garnet, as the latter has the ability to access the temple by activating the red and blue gems on the door.
