Pink Diamond is a member of the Great Diamond Authority. She was in charge of Earth's colonization, but changed her mind 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, then giving up her physical form to give birth to her son Steven, who inherited her gemstone.
