Do you have a colorless nail polish? Well, it is not just for nails actually. It can be used for your jewelry. The nail polish can make your jewelry shine and the color of the jewelry will be preserved. If you have fake gold jewelry, if you put a nail polish on it, the color will last longer and it doesn't fade as easily. Just wipe the jewelry with colorless nail polish and let it dry for 4 mins. This time your jewelry shines even more.
