Looking for a recommendation for a very strong chain (in any white metal) for 24/7 wear. My bf has a pendant he's been wearing constantly for the past 10 years or so and the chain recently broke, and I'd like to find him a new even sturdier one.
You could try Sarraf. Lots of different styles and you can choose thickness. I find their pictures a little unfocussed and unhelpful and haven’t bought from them directly so can’t comment on quality but the range of options may help you narrow down what you want.
You said he wears it constantly....so while sleeping, showering, during physical activity etc? I think any chain if worn like that has done pretty good over 10 years. The weak points would be jump rings at the clasp or possibly even the clasp itself.
I think a wheat chain is the strongest though. I wear my daily pendant on a wheat chain but I doN’t wear it for sleeping or showering etc. It is at least 10 years old BUT I check the chain regularly with a loupe to make sure the clasp and solder points to hold the jump rings are fine and to look for any possible weak spots. It carries my ER pendant and I would be devastated to lose it.
If he is going to wear it every/all day for years I suggest he take it to a jeweler for an occasional check or get a loupe to do that himself.
