The chain is extremely thin, but it seems to be very strong.  I wear two decently heavy pendants on it with no problems so far.  I actually like the thinness of the chain because I was able to easily get the pendants onto the necklace despite one of them having a thin loop for attaching.  Also, I have left this necklace on through showers and baths and it doesn't even have a speck of tarnish yet.  Looks perfectly silvery and new.  I would buy more of these, and with the great price I am even more likely to.
