Your wedding ring turning gray does not signify it's a cheap ring. Wearing your ring while you are doing laundry or dishes or other chores around the house could change the color or even your own body chemistry can turn your finger a different color from the ring. Take your wedding ring to a jewelers and have them clean it and ask how you can prevent this from happening. Wedding rings should not be worn while doing housework and cleaned at least once every couple of months in a jewelry solution and rinsed under warm water and dried well with a soft cloth.
