Fashion jewelry is the last thing to put on and the first thing to take off. Store fashion jewelry neatly in a sealed or air tight bag. Air causes metals to tarnish because of oxidation. Use a cotton cloth remove body oils from your jewelry. The cloth shines jewelry as well. NEVER USE jewelry cleaning solutions. The chemicals are too harsh.
Keep your jewelry dry. Never shower, swim, or workout in your jewelry. Always put on your jewelry after spraying your perfume or hairspray.
Remember, Fashion jewelry should be the last thing you put on and the first thing you take off before bed.
