I make silver jewellery and try to keep to ethically sourced silver. Usually, I use Argentium silver and eco (recycled) 999 silver. I have problems trying to source chains in Europe though. Cooks doesn't carry eco chain and I have a supplier in Sweden who charges a tonne and more for Argentium chain. There's an American site where I can by Argentium but I don't produce enough to make the shipping cost worth it. If anyone knows a eco/fairtrade/argentium chain supplier in Europe, I'm interested.
