Pink diamond

Pink Diamond was a Homeworld Gem and a member of the Great Diamond Authority that continued 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 life found 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 afterwards. She abandoned her little friend called spinel(you) 7000 years ago All the gems and diamonds are immortal
