All my jewelry are made from best and strongest waxed cord so there is no problem with getting them wet! Natural gemstones and crystals need to be clean time by time from energies they absorb and transform. Some times its ok just to keep them under runing spring water but some times they need more cleaning. So you can use water with little bit of dish soap, brush them with toothbrush, rinse them in clean water and leave them to dry in happy sunlight! :) Easy as that!
