Tale of Four Diamonds (SU Fanfic)

On Homeworld, the Diamonds are known to the rest of the gems as their leaders, they worshiped and treated in a familiar way to royalty. They have no known weaknesses and have the ability to reproduce daughter diamonds to carry on the dynasty of Diamonds.
The current leader of the gems, Red Diamond, reproduces four daughter diamonds at once. They are known as White, Blue, Yellow and Pink Diamonds. White is the eldest out of the four but has potent power within her that is stronger than all the previous diamonds combined. She is set to become the next ruler of Homeworld along with her sisters by her side, together they form the Diamond Authority but the youngest, Pink, has other ideas when a planet full of organic life is targeted.
