Is it required to place a metal purity marking on both pieces in a pair of jewelry? For example, if I make a pair of Sterling Silver Cufflinks. Would I need to put “925” or “SS” on both cufflinks in the pair, or can I do just one?
Hi Brian, to hallmark metal purity, the jeweler must first have their own register hallmark.
Yes, understood on that point of having a registered hallmark.
Is is necessary to stamp both cufflinks with the hallmark and purity mark? Or can I stamp just one of the pair?
I usually hallmark both pieces.
I think that the marking regulations recently changed in the US. I am trying to find them, but have yet to be able to. Can anyone give me some guidance…Rob
Hi Rob, I also recall recent changes regulations in the USA. Perhaps try MJSA.
