To keep your KONZUK jewelry looking like new, please take care to store each piece separately from other metal items. When jewelry is worn, its surfaces undergo changes. Polished surfaces become more matte. Matte surfaces gradually become shinier. Concrete will also patina over time and become darker from oils in the skin. These are unavoidable traces of wear which make the jewelry uniquely yours.
To maintain the brushed look of the stainless steel and to remove small surface scratches, a piece of synthetic steel wool, like a Scotch-Brite pad, can be used to brush along the surface. Larger scratches and dents can be removed at a local jeweler as well as more intense cleaning with an ultrasound.
