This belly jewelry is smaller than it looks in the picture - the diameter is a bit smaller than the diameter of my belly button hollow.  I like it - it's cute and adds some dangle but is still functional enough for every day wear.  The second day I wore it, the little dreamcatcher charm fell off, but I found it and reattached it - and closed the ring that connects it to the barbell so that it wouldn't fall off again.  I haven't had any skin reaction or strange rashes or anything, and I've had it in for nearly a week.  A good purchase!
