The instructions were clear, thank you but it's not I who lost the earrings. The time taken to fiddle around making a Fred Karno facsimile dowsing rod, IMO, might have been a wee bit too long...always assuming that that person had a tool capable of cutting a wire hanger or enough strength in her/his hands to break it 
I'm well aware that silver/gold and some other metals are not able to be attracted to a magnet, indeed, gold usually repels, albeit weakly.
Many posts are hypoallergenic base metal (even some posts on diamond earrings) thus able to be drawn to a strong magnet.
It was just a suggestion, as was yours.
If you know in advance that you are never going to agree with my comments, indeed, usually the reverse, may I suggest that you don't read them? It will save a lot of typing.
