We offer a collection of high quality fashion jewelry. These items are fashion jewelry and will tarnish with time. To preserve these items we recommend not spraying any perfumes or applying lotions directly on the items. Everyone's body chemistry is different and that may also determine the lifetime of the jewels. We also recommend securing the items in a ziplock bag and storing away from other jewelry pieces in a dark area(closet is best). Exposure to air causes the the jewelry to oxidize which will result in a change of color.
