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.

hi johnjsgems, thanks for the comeback, will try to find it, the shells shape up real quick, i go 7 days, then fine grit for 7 days, prepolish 7 more days, i used aluminum oxide polish, 7 days maybe i eed more time on the polish
rockpickerforever: Thanks, Jim and Dave. I agree. It happened almost exactly 35 years ago, just before Thanksgiving. She was only 22 years old. A great loss.

rockpickerforever: I am taking care of business - at Ford dealership, getting oil changed in FX4 before heading out to desert tomorrow. I love wi-fi! Will be going thru RTH forum DTs while away, no wi-fi out there. Maybe McDs in Yuma?

iamnoone: Just started my first tumble, my rocks are not going in circles like the thumler uv 18 videos I've seen online. They are just vibrating next to each other quickly. I followed instructions to the letter. Enough grit, water and rock. Am I just worrying?

herchenx: iamnoone - are the rocks already rounded or are they all jagged? is the barrel full up to within 3/4" of the top of the cone? Are you running a UV10 or a UV18 or something else?

catmandewe: Usually if they are just sitting there you have too much water. I usually add one drop of liquid hand soap also to make the grit stick to the rocks, but be careful not to add too much soap or water.

Jasper-hound: Guys, I appreciate the questions. For my own pendants, which need to be more masculine, I wear simple stones with only a sterling silver ring soldered through a drilled hole. I have found this to be a good look, and other men enjoy them as well.
