I had to get rid of them. I returned to 600 grit again and again. I reground the table three times before I decided to stop twisting the stone in the 45 degree table attachment during the polishing and let the polish spread across the face of the table at its leisure. Even though it seemed to take forever it eventually did spread across the face of the stone. The mini-facets were gone.
Some people take awhile to understand.
It took me 10 hours to make a 15 mm. Once I got the table polished, the crown angles cut fairly easy. It only took only 2 hours. The instruction book talked about an angle stop to keep from over cutting the angles. I don't think my machine has one.
