I think it depends on the cut of the crystal. Briolettes chip really easily,
etc. It's the edges you'd worry about.

With PMC we tumbled both fused class and lab created stones that were fired
in the silver. I'm sure a crystal would have been fine; I would not have
hesitated. My only question is whether a rotory tumbler would be any harder

on it than a vibrating tumbler was.

A natural crystal (rock) is full of plains and will chip. But I am quite
sure the lead that's added to glass to make crystal makes it much stronger.
Which is why they can makes such fine, thin stemware.
