Pink Diamond was a Homeworld Gem and a member of the Great Diamond Authority that continues to rule over the Gem race in her absence. Originally in charge of Earth's colonization, she took the form of a Rose Quartz after her fellow Diamonds refused to allow her to abandon the colony and spare the life on the planet. As her plans escalated into an all-out war Pink faked her own shattering in an effort to finally drive Homeworld away from Earth, taking on Rose's appearance as her default form since then. Her original form first appeared through a mural in "It Could've Been Great" and later a reflection in "Jungle Moon", making an official debut in "A Single Pale Rose".
