Not long ago I discovered how shockingly toxic most commercial beauty products are. What does this have to do with jewelry? Well, it turns out that costume baubles—another thing that so many women have on their bodies for much of the day—can also cause gnarly chemicals to seep into your system. This may not cause alarm in many people right now, but I predict that in the future, more women will take note. Just as foodies are picky about the provenance of their ingredients, health-conscious women will become more discerning when buying things they lay on their skin. Leonor Heleno, a jewelry designer that I admire, assures her customers that there’s no nickel or lead in her designs. (Her site is where I caught sight of the issue, and this is one of her necklaces pictured here.) Personally, I have been a (slightly guilty) fan of the ridiculously cheap and on-trend accessories at chain stores. Now I’m looking at those products differently.
