I think the word "polishing" is kind of misused when it comes to stones. Every operation is actually cutting, the final operation is just cutting with a very fine grit. So if a stone has a chip in it, you need to cut the chip out, and then re-polish the facet. Scratches can be removed sometimes with out deep cutting, so they can be "cut" out with essentially a lap that is both cutting an polishing. Deeper damages require cutting. The problem arrises when you cut down one facet to remove a chip, you have now lost the meet points to the adjacent facets. On a stone like this one with a complicated crown with very uniform facets you would have to recut the entire crown, and then polish it to make all the facets meet up again. The challenge here is to get the stone re-dopped exactly square to the dop, and oriented exactly the same. With simple round designs, this is easier to do. If the stone is not perfectly dopped, the you go fishing around for every facet angle. This design is hard enough to cut when the stone is perfectly aligned.
Removing scratches or small chips from a commercially cut stone is a bit easier, since the cutting is usually pretty bad and nothing really lines up correctly anyways, it doesn''t matter if you over cut a facet here and there to clean them up.
