This 18" diamond cut neck wire is a customer favorite.  It adds just enough sparkle to complement but not detract from a pendant.  Being a neck wire, it keeps its round shape and a pendant typically falls just below the little dip where your collar bones meet above your sternum.  The unique compression clasp blends in so well with the rest of the chain, you hardly notice on the odd occasion that it slips forward.  The clasp is really secure and easy to use.
