Daiwa Luvias (and in general) spinning reel stem question

Just got back from a great trip to the 1000 Islands and while there I was using my brand new Daiwa Luvias 3012H spinning reel on a St. Croix Legend Xtreme 7' MF spinning rod.  Yesterday morning, I noticed that the stem of the reel near the reel seat was scuffed with some paint loss right along where I split the reel with my fingers to hold both it and the rod.  I have my wedding ring on and its smooth with tapered edges but could this have caused the loss of paint?  I don't believe any of my other reels have this wear (but I could be wrong I would have to look).  Would it be the wedding ring or just weaker paint since I have been married for quite some time and clean/baby my gear and never have noticed this type of wear.  Not that it really matters since the reel is really awesome but just thought I would ask if this has happened to anyone else.  Thanks!
