    Acid test question?

    I found a catholic medallion with necklace. The medallion itís self was good for silver with the silver acid and good for silver with the 18k test it turned that bluish milky color. I tested the necklace park with my silver test seems good and with the 18k silver test it did not react. Meaning no bluish color or it didnít dissolve. I then checked with the 14k acid it too did not dissolve what do I have metal wIse?

    If it stands under the gold acid you may have platinum or palladium. Is it heavier than normal? Plat is more dense than gold so it will feel heavy and the gold acid will not wipe it out

    I tried the platinum acid it dissolves. It just doesnít look like gold to me if it really is 18 k

    are there any markings on the necklace? Some metals don't dissolve... maybe nickel? Could also be stainless but I don't know if it dissolves

    Itís been in the water for awhile the medallion is marked with sterling instead of .925. Maybe itís 18k just a little tarnished from the bay?

    I have found a few stainless chains, and they never seem to have a clasp, just like yours.

    That chain is SS for sure. I have several put away some where, very common in the Bay area. Dated late 40's to 60's

    I guess it's possible under certain circumstances, but, I personally have never seen 18k gold tarnish.

    Send it to me Joe it’s fake lol. I agree....SS chain....and I suspect the medallion is as well. If it’s hard to scratch that’s a tell. Use a good magnet hole it by the medallion....if the chain slightly moves you have your answer
