Did you know the best way to store your jewelry is in a zip baggie/air tight container? Many of my customers ask how they can prevent their favorite pieces from tarnishing and were surprised with my answer. Even the most prestigious precious jewelry brands store it that way. Exposure to air and all the chemicals within it is what causes the change in color and it can turn reddish or greenish color depending on the original metal. That is why I love using semi precious material like gold filled and silver filled because It is not easily effected by this like other costume jewelry. That is also why each one of your ordered pieces is packed individually in a tight zip bag. Now you know why I do what I do :-)
