How Did No Gem in Steven Universe Realize Rose Quartz Was Pink Diamond?

It was Steven Universe's biggest reveal: Rose Quartz was actually Pink Diamond. There were a lot of people who didn't think it was true, but we're just humans—what we want to know is how Rose Quartz – or is that Pink Diamond? – was able to fool every Gem she came across too? What if I told you it wasn't that hard? Steven Universe is full of Gems, and a lot of them met the rebellious Rose Quartz without realizing she was actually Pink Diamond. Some even fought alongside her, and stood by her son's side, giving us the Steven Universe we know and love.
