Gem Homeworld (Canon)

The "Gem Homeworld", or simply "Homeworld", is the home planet of the Gem race.

Little is known about the Gem Homeworld, including its exact history culture and society, although it is known that Homeworld is a matriarchal society ruled by the Great Diamond Authority. A strict caste system based on gemstone predetermines every Gem's role within society, and deviation from social norms is harshly punished. Homeworld's imperialistic and exploitative society indicates they're possibly a warlike society bent on wiping out organic life. Another possibility is that they simply don't care about non-Gem life forms, seeing them as inferior. The Gems primarily came to Earth for the reasons of building a colony and later destroying it after the rebellion.
