I love Blue Nile charms. It's been more than 6 mos now, and I wear my bracelet everyday, and I never remove it, except when I had to eat at a crab fest ;) My P and S charms now have scratches and some little marks/dents but overall, it is great quality. S has been caught on clothes, nets, etc and the connecting ring & lock are still good. I don't fear of losing or breaking it.
Another great purchase from Blue Nile. It will be a Christmas gift, so don't have the reaction yet, but I know she'll love it!
