You can’t really tell from this picture.

But I did manage to get the surface very shiny and smooth. I went through all the grades of pumice block and sandpaper from 40 to 1200, got rid of all the scratches, but still I wasn’t satisfied. The teacher made me happy again, saying that that is the best one can do because the stone has it’s own structural flaws that show through.

Anyway, that is the best polishing job I’ve ever done.
