Silver has a tendency to tarnish over time. But when it is cleaned often with a soft cloth, its shine returns. Remove jewelry before sports, swimming, showering, house cleaning, laundry.
Sea or pool water can alter our jewelry. Also, its contact with agents containing chemical elements such as: perfume, salt, air, sulphur, creams for the skin, varnish, chlorine and the acidic ph of the skin should be avoided, because they can cause oxidation.
Oxidation of silver is therefore not a manufacturing defect.
