Black Opal

(This is a Steven Universe fanfic featuring my OCs) Black Opal is a rare, prestigious gem belonging to White Diamond. Gems give her their utmost respect, almost treating her as though she were a Diamond. One of the gems who serves her is a Shadow Agate, a kind and gentle Agate who can't bring herself to hurt anyone unless it's to protect someone. Black Opal is sent on a mission to Earth with Shadow Agate to accompany her, where they are to protect Pink Diamond from the rebels and keep her court in line.
But on Earth, there is no reason their status separates them.
On Earth, their purposes don't have to matter.
On Earth, things don't always follow one specific plan.
