First, is this a type of shellyou have seen polished? Some shells will be more mostly calcium or calcium carbonate and will not polish. I have see the ones that look pearly or opalescent and I guess this will polsh - but be careful this is not a thin layer that you grind off.
Second, what did you batch look like. A small number of walnut-sized sea shells will not contact each other enough to get much abrasive action. Were there many small bits of shell or filler int he batch? A picture of the batch would be real helpful.
the shells are quhag shells, they are the hardest shells, i make wampum with them, they smoothed up real nice, used plastic pellets in the polish tumble for 8 days. last batch i did came out fine, could have been a little shinyer. did not burnish because they were really dull.
Most of the shells I do are like the one on my avatar. I just spray them with gloss paint as they do not polish. We do have a local tourist trap called the 'Shell Factory' here in Ft. Myers. The last time I went on the factory tour 20 some years ago they were using felt buffing pads and I believe tripoli polish for the big shells. You may want to try a felt buff in a dremel tool w/tripoli and see what happens.
