This maternity belly button ring has a tiny sterling silver puffed heart charm on bottom.  You won't even know you are wearing this light weight charm.

The flexible and comfortable PTFE bar is 2 inches in length. It comes with a 5mm steel ball on top. The bar can easily be shortened, if needed, for a perfect fit.  See Rethreading Belly Charms for instructions on how to shorten your maternity belly button ring.
