I didn't know that; thanks. In truth I very little care whether metal is silver or how pure; I'm unfascinated by silver, but AFAIK there are some sort of tests that jewellers know; maybe someone can tell you. Black oxide is a pretty decent cue though. Nickel alloys rust (I like to use that word for all metals; I don't know why) grey or green (depending how much copper they contain), and aluminum, while having a slightly different sheen, also rusts dull light grey.
