Emerald

Emerald (More Specifically Emerald Facet 2K7N Cut 5VV) was the founder and former leader of the Crystal Gems. Enthralled by the beauty of Earth, Emerald led her friends and allies in a Rebellion against the Gem Homeworld around 5,500 years before the events of the series, successfully driving the invading Homeworld Gems off the planet and saving the life forms inhabiting it. Emerald eventually developed a romantic relationship with a human, Eric Universe, before giving up her physical form to give birth to their daughter, Ella, who inherited her gemstone.
