Acid test question?

[rykroll]

I found a catholic medallion with necklace. The medallion it’s 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 didn’t 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 doesn’t 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

 

[zigzag]

I'm guessing stainless steel

 

[buzzhead]

Stainless will not disappear sir..

 

[rykroll]

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

X2 my guess

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.

I think this maybe my first 18k to have tarnish. Some is shadows

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

I wonder what that was alloyed with.......silver? I've never seen one look like that which was genuine 18k.

 

[OBN]

It's genuine 18k for sure, the bay is just hard on it's gold. Here is some 14k dug this past week, stained then cleaned with Mothers Mag wheel polish..

Its called "mystery metal".

No kidding.

Nine out of ten of these you will encounter will be weird NON silver and especially NON gold... AND super especially NON anything like platinum or any other metal.

Most religious items are base metals and worth only collectable value.

And you're willing to go into that water? . If it will do that to gold, what is it doing to YOU?

Thousands go in swimming every week and THEY eat the seafood... But you are correct to a point, How safe can it be.......... or anywhere, for that matter?

My god you take the Maryland crabs away and everyone would move...

The medallion it self is silver says sterling and test good for silver just the necklace was in question
