I know some people do use acrylics to paint on stone, so you probably could. You would have to be very careful applying the finish coat so the paint doesn't run/smear.

Maybe I can use relief painting, too. I have use both acrylic and relief painting on plastic and glass with a a coat of gloss sealer at the end to protect the design. Thank you, have a nice day 😺🤗
