The metals naturally oxidize over time. The darkened or faded areas due to this chemical reaction can be removed with a silver polishing cloth.
To delay oxidation, keep all SCHO jewelry away from hair products, sweat, humidity, moisture, shower, steam, watery weather and other water sports. Please store it in a paper bag or SCHO’s given dust bag with the silica-gel pebble packages when you are not wearing your jewelry.
