a tiny drop of bleach on silver will turn it black, the purer the silver, the faster it reacts. when satisfied, wash it off & re-polish the spot. if it DOESN'T blacken, it isn't silver. (clean the area beforehand to make sure there is no oil or grease/wax coating to give a false negative...)

egg yolk will also blacken real silver quite quickly, it has sulphur in the yolk part.
