Polishing. After a gemstone is sawed and ground to the desired shape and sanded to remove rough marks left by coarser grits, it is usually polished to a mirror-like finish to aid light reflection from the surface of the stone (or refraction through the stone, in the case of transparent materials). Very fine grades of diamond (50,000 to 100,000 mesh) can be used to polish a …
The Stone grader polishes the surface of the grindstone from its normal 220 grit to a finish that works like a 1000 grit stone. This is a great advantage, since you can do the fine sharpening with the same setting of the jig as used for the initial shaping of the tool.
Finishing bores of almost any material such a: sprayed coatings, CGI, Ceramics, etc. Define The Honing (Process): The honing process provides the final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores.

That looks like it was gone over with a float or a darby, should have at least been bull floated and broomed, i don't think it's a good idea to start grinding it, your going to expose the coarse aggregate if you do, probably best to leave well enough alone, your call though.
2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.
Resin bond grinding wheel can be used for higher grinding speed and higher finish. The diamond grinding wheel usually uses resin bond, because the vitrified bond diamond grinding wheel has a high manufacturing process, and the large-sized grinding wheel is often used in the grinding thermal spray process. Vitrified bond is difficult to reach ...
7. Rinse and rub the gem's facets over the 600 grit sandpaper. Pour a little water over the gem to remove the 400 grit. Remove the sandpaper and set down a sheet of 600 grit sandpaper.
