Peridot Era 1

An Off-Color is a Gem who is considered defective by Homeworld because they don't perfectly match the physical, behavioral, or functional expectations of their Gem type.
They are often treated as mistakes or abnormalities and can be punished or destroyed for not fitting Homeworld's strict standards

Sapphire is a Gem type created mainly for future prediction. She can see possible future events, making her valuable to Homeworld for planning and decision-making.
A sapphire is considered an off colour when it can't see into the future just the past (some get called Padparadsha)

A Kindergarten is a Gem facility where Gems are artificially created from the planet’s resources. Gems emerge from the ground already physically developed and with a predetermined purpose, based on the type of Gem they are. Earth had several Kindergartens created during Homeworld’s colonization.
Gems of different courts
Gem society is divided into four courts, each associated with one of the Diamonds:
White Court: Gems associated with White Diamond, focused on authority and control.
Yellow Court: Associated with Yellow Diamond, often involving military and construction roles.
Blue Court: Associated with Blue Diamond, including Gems connected to diplomacy, art, and emotional duties.
Pink Court: Originally ruled by Pink Diamond, with Gems connected to Earth and her personal court.
A Gem’s type, rank, and court determined much of their role and status in Homeworld society.

Homeworld is the Gem empire’s home planet and the center of Gem civilization in Steven Universe. It is ruled by the Diamonds, who created a strict hierarchy where Gems are made for specific purposes and expected to follow their assigned roles.
Homeworld values order, efficiency, and loyalty to the Diamonds. Gems who fail to fulfill their purpose or rebel against the system are considered defective or dangerous. The empire also expanded by colonizing other planets and extracting their resources, which caused major conflicts, including the Gem War on Earth.
