Metal Finder
Junior Member
I found a pendent that looks like goes on a chain but cannot determine what metal it is made of. It looked gold till I got home and soaked it in tarnex from Walmart and turned red. I used my gold testers on it both gold acid test and an a gold electric test. Both came out negative. Does anybody now what I can do to test for copper??? Here is a cupple pictures of it. One friend suggested it was a graduation pendent.
