Can 14k gold be a little magnetic?

Can 14k gold be a little magnetic?

I have a few sets of karat gold earrings that are hallmarked. Why do some not respond to a magnet, while other move a little toward the magnet (they don't stick to the magnet, however)? Does it mean the ones that move are not karat gold?

Hi kevenay,

Yes. 14kt gold is 58.3% gold and the rest "filler" metals that can range all over the place depending on who made the 14kt gold. It would be a good idea to test it just to be sure, even the non-magnetic stuff.

Hope this helped.

It is also possible that there is a small steel part. It is common that clasps have a small steel spring.

I've never seen gold alloyed with iron or steel, so it's more likely that there's a small piece of steel somewhere in the earring. Are they the leverback style of earrings? They have a spring, although they're usually made of nickel. There are some ear nuts that have springs in them, called clutch backs, sort of like tie tack backs where you squeeze to release them from the posts. A lot of jewelry is partially polished by tumbling. Sometimes steel shot is used as the media, and it's possible a piece of that is stuck in your earring.

Gold is not magnetic. Gold alloys are not magnetic, and iron is never used in the alloy (I do not know if it would even chemically possible to make such alloy, and it would anyway make the mass much harder to work). But it is not uncommon that some earrings and some bracelet have inside tiny parts made of iron/steel, especially in the locking mechanism / clasp. The weight of these tiny parts is unimportant, but they can display some weak magnetism.

Hi all,

while I agree 99.9% of alloys do not contain any iron, believe me, they are out there. Most if any magnetic reaction will be from steel springs etc. somewhere in the item, Like you all have said. BUT, there are alloys of 14kt gold that contain iron. believe me or not, just letting you know.Don't believe me if you don't want to. Your choice.

If the earrings were made in China, I'd believe it for sure. Iron, steel, or melamine, I wouldn't put it past them.

Well, in fact iron is used to make a blue and gray gold. http://books.google.ca/books?ei=kTzPTM820f-cB_Wz5SA&ct=result&id=ioNOAAAAMAAJ&dq=gray+gold+alloy&q=g...

Yes some old gold has iron in it, up to 25%.  Nickel is used as an alloy in gold and is slightly magnetic , to everyones disbelief. 

So when the 40% of 14Kt gold   of these alloys are used , the gold will be slightly magnetic. This hold true in older gold more often.  Always look for springs in the clasps, as well as a different (stronger) alloy gold than the gold chain that it may be attatched too. It is just simple chemistry. Thanks

I agree, I wish there was because there are too many being pulled up.
