This is Morganite!!
Morganite is a homeworld gem whose job is to do the “detailing” on pearls. Sometimes, the diamonds and elite gems would want a pearl with certain capabilities, like dancing and singing, or certain appearances, like a long ponytail or short hair. Morganite would be given a newly “born” pearl and she would program in her capabilities and aesthetics. She’s partly an engineer and partly an artist.
Morganite loved her job for most of her life and loved seeing the pearls she detailed going to “good”, elite homes. Her art was in incredibly high demand. After a while however, she started to wonder if it was morally questionable to build another gem to have certain attributes. After all, no one had “programmed” her.
Long after the war, she defected and flew to Earth, hoping against hope that the Crystal Gems were still there…
Morganite has a very laid back personality, she is quite unshakeable and not a lot gets on her nerves or disturbs her. She LOVES doing work and loves the satisfaction of a job well done. She has a very warm demeanor. She can be stubborn and uncompromising, but she usually doesn’t mind doing what others want to do either.
