No, it's just you stole Caitlyn's name, so I remembered.

Tell Steve that if she messes up your jewelry then HE will have to pay to replace it.

After the first piece or two he should learn.
Maybe lock up yours and then get some cheap 'good' stuff from Wally or a Dollar store and let her get into 'your' jewelry. Maybe get her a couple necklaces or bracelets of her own so she has hers and doesn't need to get into yours.
