| I know this comes pretty late, but maybe it helps anyway. You can use a Sunshine cloth if the scratches are not too deep and you are patient enough to work on it. Your pearl has very thick nacre even for a South Sea as one can tell from the "hammered" look. The scratches look like the pearl was transported with solitaire diamond jewelry at sometime or another. Contrary to industry mystique, pearls and diamonds don't mix well. That goes especially for transport.
