Amethyst is a member of the Crystal Gems. She is the last known Gem manufactured on Earth as a part of the Gem Homeworld's Kindergarten project, and one of the last surviving Gems on Earth. After being found by Rose Quartz and the other Crystal Gems, Amethyst helped her friends protect the Earth over the next four millennia, and often aids in the shenanigans of Steven Universe, Rose Quartz's son.
