Purple Diamond’s Mural
This Mural has not been seen by any gem for aeons due to the place where it is located being locked away and completely abandoned by White diamond.Â
No gems are permitted to access the place and there isn’t really a reason they would need to, not that they are able to anyway, the technology at the place is quite ancient due to being abandoned. (I imagine a time before warp pads and when doors had to be completely opened manually.)
When Purple Diamond emerged, she never really lasted long on Homeworld before mysteriously disappearing. She never got a chance to colonise nor did she get to meet Yellow and Blue Diamond as they were still incubating when this all happened. (Probably for the best.)
She did have a pearl who is currently bubbled away with her mural.
