Scratched surface on Granite floor tile.

[Spanish Joe]

Hi! Can anyone give me any advice on how to remove,or diguise scratches I have on my Granite floor tiles (which are black and have a gloss finish)??
I foolishly used a "scotch-brite" type of scouring pad on a tile, to remove a difficult to remove mark...you've guessed it, I've permanently scratched the gloss/glaze of the tile's surface.Doh! :(

I understand that I might be able to improve the damage using a "tile-sealer", which is a clear liquid that is applied to the tile. (I have n't tried this yet.) Any ideas/solutions would be most welcome. Cheers. :D
