Diamond Polish
External features that should be noted are Polish, surface blemishes & extra facets.
The polish of a diamond shows how well the diamond was finished, how clean , shinny and straight edged the facets where cut, if any traces of minute or microscopic lines or blemishes were left by the polisher plus whether any marks are visible on the stone. A well polished diamond is more brilliant than a poorly polished diamond. Other marks can also be scratches or tiny chips, diamonds may be damaged if roughly handled together.

- P = Poor
- F = Fair
- G or GO or GD = Good
