While every little corner on this piece has been sanded to round comfort, it's still not a good match with, say, a loosely woven scarf. It's a great match for a t-shirt of turtleneck.
All pendants come with the chain with which they are pictured. Unless otherwise noted, this chain is 16inches long, and will fall about midway between the neck and the decolletage on an average woman. We realize that measurement is a bit biased; our pendants are unisex and we are happy to provide longer chains if desired.
