Depends how big they are.... But, Why would you, Far better cutting them in half and polishing the cut side... I really think they will just break into pieces... The action inside a Tumbler is very violent sometimes...

A few that have been cut and polished on a flat lap and one that has been skin polished.
 
Great looking eggs, Dave!

I was wondering the same thing recently after going to town on the rhyolite with this egg, thinking the tumbler might be a easier way.

After cutting this one though, I'm fairly sure it would have cracked into pieces in a tumbler..
