The European Directive, 76/769/EEC - 12th Amendment (94/27/EC) was enact to prevent sensitised persons from suffering allergic reaction when wearing jewellery and other items. The important thing to note here is that the law applies to all jewellery (including costume/fashion jewellery) and other items that come into contact with the skin.
