Terr, Amethyst streched out her legs and arms in Steven's Birthday and she was fine.

But to debunk this theory...

1. Rose's gem shape. Yellow & Blue both have diamond-shaped gems, while Rose has a circular pentagon.

2. The Answer. Nobody referred to Rose when she invaded as Pink Diamond. Clearly if Pink Diamond just rebelled and changed her name, people would still refer to her old name. She was just a "rebel."

3. Her Pearl. Yellow & Blue's Pearls both are yellow and blue and have gems on their chest. If Rose was a Diamond, she would likely have a pink Pearl with a chest gem, not an almost-rainbow Pearl with a forehead gem.

4. How Peridot failed to see that Steven was Pink Diamond, despite being a huge fangirl and knowing practically everything about them. Oh, and by the way, Jasper refers to Pink Diamond as Rose Quartz.
