Please help me identify, thanks
 

You need a neodymium magnet. Here’s a great video showing how this guy checks his silver. Hopefully ShinyShores has a sterling silver piece!



I was mainly talking about silver plated copper which he didn't talk about in the video, I forgot nickle silver was a thing. So I guess you were right in that you can distinguish between those two with a magnet. I wonder if it works for copper too?

Also, I still am not sure of the science behind it but I think might have more to do with Lenz's law than diamagnetism.

One can’t work without the other. Lenz’s law works because metals experience diamagnetism. You are right in that it is Lenz’s law that causes the drag on silver. What puzzles me is why it doesn’t work on silver plated copper base metals (such as brass, bronze, nickel silver and some pot metals) even though they are composed of copper.... they seem to have no reaction to a magnet.
