Love this charm.  It fits beautifully well on my Pandora...and represents myself & my 2 girls perfectly (and I LOVE the 'mother/child' style...I have a necklace w/1 child...was glad to run across this charm w/2!).

The charm does seem to be Sterling (IS stamped .925), and shows no wear & tear except the fact that it's on a bracelet that's worn daily.  I love the charm and it's design & construction.  I would definitely recommend it (or it's similar models) to anyone considering it.
