very nice! have no experience with them, sorry. I would think they would tumble quite nicely though.

Thank you very much! The problem is they are just so soft if you tumble them longer than a few hours they start to break down.

oh no. Maybe try a fine sandpaper. I use 1200 grit found at my local tool store (harbor freight) to hand polish alot of my rocks.

I have cabbed this stuff before and it is a very soft rock, a 4 on the Mohs scale, you can hand polish these with fine grit, I have even used another rock to rub it shiny

Very nice looking rocks.
