>>929395161 - Made by White Diamond... gift to Pink Diamond. On the occasion of her first colony.
A nice gift, but... one with a hidden sting: White Pearl was given the ability, equipment and programming to shatter Pink Diamond, should the need arise. Of course the Pearl did not know about it, so she could serve as well as any normal Pearl.
2 - Why would White, presumably the oldest, most powerful and most fearsome Diamond, want to destroy Pink, the youngest and least powerful?
To maintain the purity of the Diamond Authority.
Perhaps she wasn't even the first Pink Diamond. Perhaps there have been differently-colored Diamonds before...
3 - So the occasion of the shattering may well be that Pink Diamond was starting to lean to understanding the rebels' point and was about to negotiate peace with Rose Quartz.
Irony of ironies: the hapless White Pearl, unaware of her true mission like a good little sleeper, had joined the rebels because, at some level, she knew she was different.
But even as she was guarding her beloved Rose Quartz, and the peace talks actually went well - something inside her said "Now." And when she came to her senses, Pink Diamond lay shattered and Rose Quartz was screaming.
4 - Why would Yellow Diamond cover this up? Because she agrees with White, to an extent, although she would NEVER have shattered Pink... she loved Pink. But what is done, is done, and she also loved Blue... and if Blue knew the truth, she would turn against White, and White would destroy her as well.
