it could be a painting.... there are several methods of recording images that predate the invention of cameras. :P

But there are two important things to ponder. The Crystal Gems have been on Earth a long time. Steven was born recently.

It would seem that the CGs have been on the run from the other gems for a long time. Why? That is a hard question.

They said Rose was trying to cure the corrupted gems, and we saw an episode where Amethyst almost became one. BUT.... We don't quite know HOW gems get corrupted. Amethyst and Lapis had their gem get cracked and there is that handful of shards that Pearl had. but the Centipeetle didn't have a visible crack.
