I just read this article in our local newspaper and find it VERY disturbing.
"Barred from using lead in children's jewelry because of its toxicity, some Chinese manufacturers have been substituting the more dangerous heavy metal cadmium in sparkling charm bracelets and shiny pendants being sold throughout the United States, an Associated Press investigation shows.
...Cadmium is a known carcinogen. Like lead, it can hinder brain development in the very young, according to recent research.
...Some of the most troubling test results were for bracelet charms sold at Walmart, at the jewelry chain Claire's and at a dollar store. High amounts of cadmium also were detected in 'The Princess and The Frog' movie-themed pendants."
Even more reason to shop handmade.
