[Jewelry making - Article 00933] - [Orchid] Tarnished copper -- another question

    I usually just let my copper tarnish and, so far, none of the people
    who've bought it have complained. It seems to have "darkened" by the
    time I've finished a piece--I do wirework, so it's in constant
    contact with my hands, and I assume this is why. 

    But...I decided to donate a ring to an auction and thought I'd clean
    it up a little, so I used a rouge cloth. Whoops! It turned gray!
    Really weird looking...Can somebody explain this to me? Is it the
    silver residue on the cloth or some strange chemical reaction with
    the copper? Do I need to pickle it to get it off? In this case I
    don't think that would be wise, because it has a carnelian in it... 

Gratefully,
