When you use a file, there will be stirations (or file marks), and these are not wanted to be seen.
I suggest using (as shown) a rotating disk of "Emery" grit. These wheels smooth the surface, as well, not leaving any deep gouges. 
When new bearings are created, it is required not to have any spaces where the girdle of the stone is resting. The claw should envelope the Girdle rim completely.
No matter the size of the stone, the depth of the bearing should be equal on all sides of the cluster of claws.
The combined angles between the "Table and the Pavilion" facets will be at 43.5 degrees. This rule will allow the light to be reflected evenly and give the viewer good reflected light.
