While fashion jewelry is also commonly referred to as junk jewelry and costume jewelry, both terms that make the jewelry sound worthless, taking good care of it is an absolute must. One of the most important things you should remember about fashion jewelry is that unlike fine jewelry that is made of precious metal and stone, it will tarnish and fade and can look quite unsightly if not cared for well. Fine jewelry can be restored to its original state by polishing and buffing. You will have no such luck with your fashion jewelry.
