Hi Nicole,
Yes, you can sand the resin off the bezels. Be careful though — if the bezels are plated, it wont take much sanding to sand the precious metal off as well.
If you have a ring of resin around the edge, you may be lucky enough to snap off the resin instead of sanding it. You can see what Im talking about in this video on our you tube channel: http://www.youtube.com/watch?v=zTAYTBEQrkk
Good luck!
