Hello jewelry hunters and everyone one else who might give me an answer. I just recently started doing more coin & jewelry hunting. I mostly do relic hunting. My question is probably pretty simple for you experienced jewelry hunters but not so much for me, i recently have found a couple "gold" rings and don't have anyway to test them, they look different in that one looks like gold and the other looks like 'not so much' and they both had an id about 28-30. To the question, " does Plated id different than Non plated? Also for you experienced gold jewelry finders what is the usual difference between the two? I was thinking since Plated probably has copper or other type metal as primary it would conduct higher than non plated....Also they have readings inside but really can't make them out, even with a loupe.
