>>111425312It's probably as permanent as a fractured leg bone for a human is; never the same as they were before they were broken, but the leg can be stood on and not cause pain if healed properly.
I would argue that because these horns and spikes are integrated into the various gem's appearance, even incorporate the color scheme of the gem, that they're as healed as they can get without there being a degradation risk.
Jasper meanwhile has a set of corruption horns that are not her own and don't match her natural color scheme, which would follow through that she's not actually fully healed. She's refusing to reintegrate into her personality what her mental damage is, so the coloration remains seperate.
If the writers for Jasper or the other corruption-victim gems were smart
(implying) they WOULD gradually reduce and smooth the features back to normal forms, and relax the colors back into the natural scheme for that gem. So it would be a non-permanent, though slow morph and return to normal.
