Caring for your jewelry starts with proper wear. That means knowing when to put your jewelry on - and when to take it off.
Put jewelry on after applying makeup, perfume and hairspray. Also, handle gems and pearls as little as possible, since skin oil can build up over time and dull their appearance.
Remove your jewelry if you're going to do any manual labor, including housework. A bracelet can be easily broken or bent if it catches on a hook. Gems, even diamonds, can chip or crack if they're knocked against a hard surface. Another danger comes from the harsh solvents used in cleaning, which are not good for any kind of jewelry and particularly harmful to pearls.
If you wear earrings, it's usually best to remove them while you're having your hair styled. That way the stylist's comb won't catch them. Never wear pearl earrings or necklaces while you're having your hair colored. Some of the coloring agents contain alcohol and other chemicals that can mar the luster of the pearls.
If you're right-handed, think about wearing a bracelet or watch on your left wrist since you don't use it as much as your right. The opposite applies if you're left-handed.
