Here's FMG's, R-N-T's, & Monsterslayer's opinions on the use of their wares for children's jewelry. None really have a clear disclaimer other than listing the CA lead class level about the making jewelry from their raw materials being sold to customers in CA.
As for what the supply sellers are saying on a description page for an item maybe one thing but on another policy page they warn you away from using their materials on a child's product. Actual if you read some of the disclaimers from some of the more popular jewelry supplier's you can see that they are covering their @$$ pretty well by stating that none of there supplies are suitable for children's jewelry due to the CPSIA.

"Are items on this site suitable for children's jewelry?
The products on this website are not designed for or intended to be used by children 12 years of age or younger. The Consumer Product Safety Improvement Act of 2008 (CPSIA) sets limits of, and testing requirements for lead in children’s metal jewelry. We have not attempted to test the products on this website for conformance to CPSIA standards. If you manufacture jewelry for children, you are responsible for testing that jewelry for lead and maintaining compliance with the CPSIA. " from near bottom of page at
