I want to send some pendants to a friend in the US - I am only charging the cost of the silver, my time is a gift to them.

They are overweight for hallmarking though. If they are going straight to the US do I have to get them hallmarked? I have no problem in describing them as "white metal" and they'll be about £15 worth of silver in each one. I know the US has no requirement to hallmark so once they get there they are legal but these won't ever be sold even in the US.

I've done a google search and am getting both yes you must hallmark and no it's fine not to!

Does anyone know for sure please?
