[Source] chain in sterling silver

Jewelry Discussion

Hi all, While we’re on the subject of chain; does anyone know of a
quick easy method to tell if a used chain is sterling? I wouldn’t
mind buying used chains and giving them new life in my work but other
than clearly labeled pieces I’m not a great guesser.

Thanks,
Pauline

As most cheap commercially made chain is composed of iron wire
electro plated, a simple magnet will give a quick answer. If the base
metal is non ferrous, then that is a whole new game and far more
difficult. Bet you’ll get lots of replies on this one! cheers, –

A small addition to John’s article,lots of chain are made out of a
copper alloy since plated with silver.On those ones,you could run a
magnet over it during your lifetime not giving you any good result. A
easy to go proces would be the use of an ink eraser.Just rub it over
the chain and if the copper doesn’t show up … you’ve got a hit
!! I have to admit that this procedure is not waterproof because it’s
depending on the thickness of the plating,but it’s a start and surely
not expensive.

I’m aware about a procedure with acids but I’ve never tried this one
and therefor I don’t want to mention about it. Regards Pedro
