I ordered this knowing other reviewers said the chain was a little flimsy.  I agree with that assessment and had already planned to substitute a black silk cord.  I also made the cord longer than the original chain.  I do like it and the amethyst stone is a very nice dark purple.  You could certainly substitute a waxed linen cord or a leather cord.  The opening is large enough to work with a variety of cords.  The price is low enough to make this doable.
