I bought this chain to suspect a pendant received as a gift with matching earrings that had a circle thing going. I wasn't sure it would work with a pendant (visually), but it seems to work great... just make sure the pendant has a large enough keeper for the chain to go through.

As described, the links are about 5.5mm, which is a smidge less than 1/4". The chain is lightweight, but sturdy. It's very shiny, but of course since it's sterling, it will patina with time. I love that the links also work as one end of the clasp... this means that you can easily wear the necklace at a shorter length (it's as if there's a self extender there) and also that it's easy to wear as a bracelet, as another reviewer mentioned. It's just slightly frustrating that the round clasp is about the same size as the links and that it's sometimes hard to find the clasp.
