Necklace on a silver chain with a silver rib cage. Lenght of adjustable chain: Shortest possible 46cm / 18 inches and longest possible 56 cm / 22 inches Materials & care Metals can be worn in water but can change color in geothermal water or water with high levels of minerals or oxides (sulfur). Cleaning the metals is not necessary unless you feel they have lost their shine. Then we recommend using a jewelry polishing cloth to rub off the tarnish. Take your jewelry off if you're involved in any activity which could scratch, knock or bend it. Much bending of metals can cause cracks that can end up with breaking. Please avoid using liquid jewelry cleaners as they can be toxic.
