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.
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
Is there a way to close old posts??
I agree, I wish there was because there are too many being pulled up.
