Every time that I get this type of scratch (always during sanding) it is from a small chip of Obsidian that comes off because I have gotten a top  edge of the piece against the belt and the belt drags the chip across the slab/cab. I resolve it by taking a scrap of material and working it vigorously on the belt. This will dislodge the chip.

Did you happen to get to close to the outer edge of the polishing pad. The edge area can be a bit rough. I think I have had a similar situation happen. Eric(Ajo)

You're correct it did. But I think it is doing it in the center as well. When I looked at it carefully I saw the little white specs all throughout the center of the wheel.  The odd thing is that they glimmer in the light. I don't think grit contamination would glimmer.

This problem has been going on for a while, and it is doing it with all types of stone. The obsidian cab was used for two purposes, one to give it a higher gloss after tubmling, and to trouble shoot. And boy did those scratches show up! Since the obsidian has been tumbled there is not edge to catch. It is nice and rounded.

Two years and 200 + cabs.
The 14k and 50k right after it look the same and they have no problems. It's well preserved because by the time a cab gets there it's rounded and smooth.   This is a new problem. It only started putting scratches on cabs a few months ago.

I think that's my next step. I scrubbed the &%^# out of it last night and the little specks did not come out.

Wow. That was easy. I called them expecting to have to explain and get a return authorization number or something. They just said send it back and they'll replace it if there is a problem.
Thanks!
