Don't wear your sterling silver jewelry in chlorine water. The use of hair spray, make-up, hand lotions and perfumes can cause jewelry to dull. Put your jewelry on after you have used any of these to prolong their luster. Store your silver in a cool, dry place, preferably in a tarnish preventative bag or wrapped in a soft piece of felt or cloth. It is a good idea to bring your pearls in to your jewelry at least once a year to have them restrung.
Normal wear tends to weaken and stretch the threads on which pearls are strung.
When you have your pearls restrung, make sure they are knotted between each pearl. This will prevent the loss of pearls if the string should break. Don't wear your watch while swimming, bathing or doing, hot, strenuous work unless the degree of water-resistance was clearly specified when you purchased the watch. Replace broken or scratched watch crystals promptly. Even the smallest crack can let in dust or moisture that can threaten its accuracy.
