Describe your suggestion.
Spreading prismoss by applying bone meal has a chance to grow prismoss sprouts. I think it should grow prismarite crystals as well.

Additional context
As far as I can tell, prismarite is not renewable. This would also make prismaglass and the other 2 prismarite crystal shapes craftable since they can already be made from normal crystals.

because the original idea was to have this as a rare decoration but because of an oversight on my part they're much more common than I want. this may change in the future but for now I'm pinning this and closing it for future use

They could spread like mushrooms within prismoss biomes only. If the rate is slow enough, they would be technically renewable but requires massive farms to get a decent supply.

ohhh thats actually a good idea, ill keep that in mind!

it was something I considered but prismarite crystals are non renewable by design so at least for now thats intentional behaviour

Why are prismarite crystals non-renewable?

Renewable Prismarite would be great, if you are looking for other options:

maybe an interaction to turn amethyst into prismarite? Either as like a crafting recipe or something more "in world" like amethyst being converted into prismarite when nearby prismoss is bonemealed
