Hi Jima

    I have seen your work from some of the shows and enjoy it. As I have
    stated in my posts on this topic the corrosion rate is dependent on
    environmental and body chemistry. There are several variables but I
    have seen gold copper rings severely corroded in very short periods
    of time (less than a year). The copper silver combination will have a
    lower voltage therefore a slower rate of corrosion. In some cases you
    will need to look with a loupe to see the corrosion but it is there.
    Sometimes it is obscured by the burnishing effect of day to day wear
    and you will not notice the gradual erosion of the copper. My reason
    for bringing this up is just to make people aware of the potential
    for a problem.
