Regardless of the type of jewelry you should obviously try to prevent it from being scratched, knocked or banged. Even if damage doesnt appear visible immediately, knocking jewelry can often lead to unseen damage. Over time this damage will build up or progressively worsen until your jewelry becomes irreparable.
Should your jewelry suffer any damage you should have it seen to as soon as possible. Take it your local jewelers and ask their opinion. In most cases they will either be able to fix it themselves or send it away to be repaired properly. Super gluing any piece of jewelry yourself is a bad idea.
Many chemicals can damage jewelry and you should stay away from chemicals in general. In particular, cleaning fluids, chlorine and bromine can have a detrimental effect on some jewelry. Take off any rings or other items and leave them somewhere safe until youre finished. Direct sunlight and extreme hot or cold conditions can also weaken the metal or jewel.
Use a jewelry cleaning cloth on metal jewelry and clean regularly using soapy water but ensure that you rinse it off thoroughly when youve finished cleaning. Use a very mild cloth to dab it dry and dont rub it too vigorously. You should also take care when storing jewelry. If you dont intend to wear it or show it for some time then place it in an airtight bag away from heating or particularly cold areas. These simple maintenance tips should ensure the integrity of your jewelry for many years.
