When you are not wearing your sterling silver, keep it in a ziplock back with some rice. Humidity is what tarnishes silver so keeping it air-tight with something to absorb the moisture will keep it sparkling for a long time! Also, most jewelery counters will sell a polishing cloth. (under 10$) this is a great investment. The trick is to NEVER wash them! they will last for years and help keep your gold and silver sparkling like the day you bought them!
