I bought these with a gift card someone gave me.  Beautiful, light weight, and delicate.  I am the type to put a pair of earrings in and wear them 24 hours a day for a week or so before changing.  These are very comfortable.  Only issue is that when I sleep or shower in them, sometimes the heart gets hooked up on the back piece and looks like I lost the chain/heart - but just had to flip them back down. Just startled me the first time!
