This is a ring I found yesterday, it was white/scratched and marked .925. My wife liked it so I tumbled it in stainless steel shot, when I took it out this morning it was perfectly and completely copper plated. I clean almost everything I find one way or another and have had this happen before when a stray penny gets mixed in with silver, but nothing as perfect as this. So I acid tested it just now and it is silver but even before I applied the acid I could see clean silver on the ring where I rubbed it on the stone. I thing there was copper filings in my tumbler, I've washed it so it doesn't happen again. Its not a collectors piece just a pretty ring, Any ideas how to get the copper coating off ?
