Do lab grown BISMUTH crystals contain arsenic? Are they safe to wear against the skin?

0 votes
I see that jewelry is made using lab grown BISMUTH for rings and pendants, but I want to use it on post (aka stud) earrings. Is it safe for long periods? I think I read that it contains ARSENIC. If not, how much of a backing barrier do I need?

I never heard of synthetic bismuth containing arsenic, though bismuth may have some mild toxicity effects. I wouldn't suggest prolonged exposure directly on the skin.
