Will not come off
Color: Gold Paperclip
Do not, do not buy. They clamp so tight that I had to have them cut off my ear.

Very nice gift necklace
Color: 10-Oct-Lab Grown Pink Sapphire, Style: L
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.
