Sterling silver tarnishes with time and wear. Avoid contact with water, chemicals, perfume, and cosmetics. If left unused, keep it in a cool, dry place stored in an airtight plastic bag or a jewellery box. Since sterling silver is a soft material and can scratch easily, store pieces separately. To remove oxidation use a polishing cloth. Small and delicate pieces may bend under pressure, avoid wearing your jewellery during sports activities and housework.
