You are able to fit BOTH Pandora beads AND Chamilia beads on Pandora bracelets. Some websites I'm reading are saying that you CAN fit Pandora beads on Chamilia bracelets but my friend is a Pandora retailer and doesn't advise that you should do it. That being said, she has both Chamilia beads and Pandora beads on her Pandora bracelet as do I and I've never had a problem!
