Tumbling CZs

Hello, Can anyone help me?

My question is: Can cast-in-place CZs be put through a normal
tumbling process to finish the piece or are they (the CZs) abraded,
and therefore ruined, in the process?

Thanks for any insights.

CZ is far too brittle for what you propose. It scratches and chips
VERY easily. Even in normal wear in a ring, it is surprising to see
them last for more than a very few months.

Huh. I tumble CZs in stainless steel shot all the time with no
problem.

Really? Look at them with a loupe and tell me that.

I don’t find any problems under 10x magnification. Perhaps it has to
do with the amount of time tumbled? Type of shot? Luck?

Interesting. My guess is that whatever fluid or cushioning you are
using prevents much of an impact from the steel shot; but then how
would it burnish or polish?
