I like the concept that all the diamonds had that "Younger" stage, like Pink's bratty attitude in Jungle Moon. They're kids.... But gems dont know what kids are, & gems don't know how to raise kids.
Headcanon - All Diamonds were created at the same time, but White being the largest took all the energy first so she could form. Describes the other diamonds to take much longer to take a physical form, pink would be the very last after Blue & yellow are "grown". AKA better disciplined in White's eyes, in a few thousand years.
White told Blue & Yellow that diamonds are perfect by default, but she is the peak of perfection! So Yellow tries her hardest to imitate her, upsetting blue a bit as she thinks that they were perfect already.
The 2 train w/ White a lot, they don't have their own pearls yet but they desperately want one! Yellow accidentally broke one of white's old ones once.... But she wasn't punished for it, white says they're very replaceable. At the moment, while they are still young White controls every aspect of homeworld. Shes not quite sure what she'll give the last one when she takes her form but she'll figure it out, maybe...
