Hi ladies, I just bought this topaz stam. I LOVE it, but it has a few spots on it where the lovely topaz color has worn away a little. It looks like it might have been from the chain rubbing. It doesn't really bother since I bought this to be an everyday bag, but is there anything I can do about these little "bald areas?. Also I want to take good care of her, so any ideas on preventing the "balding" from going any further would be great!(you can see the bald area on the lower right hand corner of the bag in the first pic)
