Honestly - I found this to be of equal quality to the well known brand necklace of the same type (birthstone and initial) that I also bought - and this one cost less. It looks lovely. It made a great gift for my niece. The chain is quite delicate - but most of them are, these days. I definitely recommend for the younger ones in your life - teens on down. It was a big hit.
