Removing hairline scratches on crystal..Cape Cod or Diamond Paste?

[sampelligrino]

Hey TRF

Knocked my SubC against a table at a wedding last week and noticed a hairline scratch on my crystal that I can just barely feel with my finger nail and can see in sunlight. Scratches on my bracelet I don't mind but this is driving me nuts for some reason.

I've been doing searches on the forums and found that people have had success removing hairline scratches on the sapphire crystal with Diamond paste and/or a Cape Cod cloth. I was wondering which of the two you guys you guys might suggest? Figured I'd go this route first before having to actually replace the entire crystal.

Does my SubC have AR coating, and will buffing the scratch out remove that? Also, will the crystal be good as new or will there be a "buff spot" where I polished the scratch out on the crystal?

Thanks as always fellas
