Hello! I'm a beginner jewelry maker currently focused on sterling silver/ copper wire wrapped jewelry. This is mostly just a hobby, but I'd eventually like to make enough pieces to sell in local crafts fairs or potentially online. I'm wondering what kind of safety requirements need to be met to do this? For example, I know there are certain regulations regarding lead content in adult/children's jewelry that need to be met. As a beginning artist, how does one show that I'm using safe materials? I've mostly been ordering from US companies for my sterling silver wire (Fire Mountain Gems for example), and they do state that they follow US safety laws, but will that pertain to Canada? Does anyone know any Canadian suppliers of sterling silver wire that can prove they're following Canadian safety regulations? Would I need to send my stock out to labs to get tested?
