I may go through and put it in each listing that applies. Most of my jewelry contains vintage glass, which may or may not have trace amounts of lead. The austrian crystal, I am sure, does. And unfortunately, I just don't have the $$ to get my supplies tested.
As it were, a child-safety warning would still be a good idea regardless (choking hazard, not intended for children age 12 and under), considering I did have a parent (many many moons ago) ask to purchase one of my smaller chokers for their young daughter, who participated in beauty pageants. Said parent never made the purchase, but it did make me think.
The majority of my stuff isn't intended for kids age 12 and under, but you never know - and I hadn't considered pageants until that inquiry, many moons ago.
