Rose Quartz, or Rose for short, was the founder and former leader of the Crystal Gems. Enthralled by the beauty of Earth, she 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 Homeworld Gems off the planet and saving the life forms inhabiting it. Unbeknownst to everyone (except for her Pearl), her identity as Rose Quartz was a facade to hide her true identity as Pink Diamond.
