I found that pismo clams shells will take a good polish when run through the tumbler. Start with 120/220 grit. All that happens with the 60/90 grit is that you break up the shells and get no grinding. You lose a lot of volume, so you need to make very liberal use of plastic pellets as filler. Taken without the camera flash in a light box: Camera flash used along with the lights for the light box:

Those look like they'd be great for wire wrapping

Interesting idea, Steve. Never occured to me to try polishing them. Paul
