Hi guys I was hoping someone would be able to help me with this. I have a commission for a white gold 18k wedding ring, the customer asked what alloy etc I would use and I got the info off cookson and it was all good. Then I went to buy the stuff today and the solid solder for sale doesn't comply with EU nickel regs. I'm presuming there is a good chance of a nickel allergy given she asked about the alloy, and I realise the solder join should be tiny but it will be in contact with her skin since it is a ring. Does anyone know where to source solid nickel free solder, I'd rather not use paste for a ring, or if the fact that the rest of the ring is nickel free means that the tiny amount of solder will make the whole piece EU regs compliant?

Any help appreciated!
