Our jewelries are set to last a lifetime as these are made of stainless steel. They do not tarnish nor there is a need for a maintenance. However for color plated jewelries, avoid contact to harsh chemicals or oil based products ex. perfume, soap, lotions, to keep the plating last longer. For steel tone jewelries, color will not change. Our jewelries can be kept in its best quality by using a polishing cloth available from us. We also recommend just wiping with semi damp cloth to return the luster.
