It's not confirmed but the possibility was reinforced.
We saw a bunch of amethysts with huge amounts of natural variation. Different eyes (both color and style), different skin color (ranging from lavender to red wine), and most importantly different sizes. We also got confirmation that there were hundreds or thousands of other Rose Quartzes who got bubbled.
This all means that it's completely possible there was one rose quartz (possibly a beta kindergartender) who was small enough to be mistaken for human and had green eyes and hid amongst humans, and the pre-existing evidence for Sheena being a Rose Quartz still stands.>>88851421
But Garnet wasn't and she has pink diamonds on her heels. also, they would have gotten rid of the diamond designs if they didn't respect PD
