I made my Gemsona!!
Vivanite was made by Yellow and Blue to be a gift for Pink after she completed her first colony. Seeing how fond she was of all the organic life, they decided to utilise it to create a new type of gem. Vivianite's purpose is to collect, preserve, recreate, and wipe out organic life. While environmental factors make them difficult to produce, they take far fewer resources than creating numerous zoos for all the life Pink grows attached to. Vivanite absorbs, corrodes, and assimilates life forms into their gem, in a fashion similar to fusion and how a pearl stores something in her gem. At their discretion, they can reproduce any creature they've absorbed, albeit more gem like, but still organic. This provides them with a large arsenal of ways to exterminate native organic life, making terraforming a much easier task. Being made from organic life, they are able to fuse with it. They are the only non-Steven to be able to do so.
The first and only Vivanite that emerged fully functional did so a few days before Pink diamond was shattered. After which, their production was put on hold, and Vivanite bubbled. Blue's grief made their creation ban permanent. She couldn't bear to create any more, but neither could she shatter or use the existing one, so they were bubbled. Hence, their uniform still representing pink. They were finally unbubbled during era 3, but their production was not reinstated due to Steven's discomfort with the process. And that's the story of Pink diamond's Pet keeper and Exterminator.
