    It is copper or a copper alloy, imo.
    I ran it under the AT Pro. Maybe not the most scientific way to tell, but it rings up a 50, and has a moderate tone. Copper would be 80+, and higher pitched. Pre 82' pennies are always ringing up around 80-81, and they are 95% copper if I'm not mistaken.

    Thanks
    Yes, For some reason gold mixed with other metals, anything under 24k, will have a reaction to certain things. What? I have no clue! I believe it's the other metals reacting and not the gold. I have no clue what you found is or isn't. But I have seen it dark a few times. At first, when I was buying I was told gold won't tarnish. I learned later that that isn't true, and have bought gold items that others would pass on because of that belief. No idea what causes it to turn.

    Anything! Baking soda, even a jewelry polish cloth. Like people have for their silverware sets. Usually it will come right off if it is gold. You could even use car polish that has a real fine grit. You can't really hurt it if it's gold. Just use something fine. Heck real fine steel wool will work too. It will just need a final polish after that. I've heard of people even using toothpaste. It shouldn't take much work to get it polished if it is gold. A few swipes. I also knew an older lady that cleaned her jewelry in tea. No clue what kind.

    The quickest way to find out is take it to someone with nitric acid. Usually, jewelry makers or repair people, some coin shops, and maybe even a pawn shop. If they drip nitric on the copper looking areas and if it is copper? It will fizz and turn green. If that happens? Don't waste your time with it, It's fake. Sometimes repairs are done and clasps or rings get changed, never count on those as your indicator, have them check the actual chain. If I had to guess based on pics alone? I would guess that it's no good, but? That doesn't mean anything! I've seen some odd stuff.

    Thanks Nitric, I'll give it a try. Stay tuned, I'm going to post pics good, bad, or ugly. But it's going to have to wait a few days.

    Well, better late than never. It actually cleaned up pretty good, but definitely not gold. Case closed.

    OLDER 14K CAN BLACKEN OR "TARNISH" IF YOU WANT - IF THE OTHER PART - (THE METAL USED IN PLACE OF THE GOLD= THE OTHER 10K IF YOU WILL)
    IS SILVER - I HAVE FOUND OLDER GOLD MORE THAN A FEW TIMES WHERE SILVER WAS ADDED TO THE GOLD INSTEAD OF COPPER OR NICKLE OR WHATEVER
    AND IT WILL TURN DARK A FEW DAYS AFTER I SHINE IT UP - MINE ARE NOT PLATED - THEY TEST POSITIVE AS GOLD
    I FOUND AN OLDER 10K CLASS RING THIS YEAR THAT SHINES UP NICE BUT IF LEFT ALONE IN DISPLAY CASE IT WILL SLOWLY DARKEN
    SO I JUST LEAVE IT ALONE NOW- IF I EVENTUALLY FIND THE OWNER I WILL SHINE IT UP FOR THEM -- I BELEIVE COMPANIES BACK THEN
    THAT USED SILVER AS AS AN ALLOY WERE NOT AWARE THAT THIS WOULD HAPPEN - IF YOU NOTICE THEY DONT USE IT ANYMORE

    Toothpaste will brighten it up or a jeweler’s cloth.
