You have a few obtiions: 1. you could gold plate what you made and
hope to match the color of the chain; 2. polish off the plating on
the chain and hope you don't get the chain caught in the buff; 3.
electro strip the chain and polish it, or; 4. Bomb the chiain with
cyanide and hydrogen peroxide. There is no way to win, it's a pain
in the neck, good luck j dinola
