All silver jewelry should be stored properly in soft, anti-tarnish bags in a cool, dark place. The lower the humidity, the better. Some people add a piece of chalk, a packet of charcoal, or even silica gel to the bags to help remove moisture. You know what? Bathroom has the most moisture. I am also so guilty of this as well, so do not store or keep your silver jewelry in the bathroom. Remove rings, earrings, and other silver pieces before showering, swimming, or doing dishes, and be sure to put your jewelry on last, after all your perfumes and lotions have had time to sink in.
Another way to prevent tarnish is to simply wear your silver. The daily friction of life actually does wonders for making silver shine
