Suggestion is to place the necklace into a small closable plastic bag or to wrap it in layers of tissue paper for protection. This can be placed into a small jewelry box and then into a padded envelope for further protection. Just insert the tissue paper packet into the padded envelope if no small box is available. Seal the padded envelope, address the package, and take it to the Post Office branch near you for postage and shipping.
