Our product is gold plated. Since it does not contain nickel, it does not cause any allergic reactions. Taking care to avoid contact with perfumes, creams, disinfectants and similar chemicals prolongs the life of the product and prevents it from darkening. For hygiene reasons, returns are not accepted when the products are opened. When you do not use the jewelry you have purchased, you can keep it in its box to reduce its contact with oxygen and use it with its first-day shine for many years.
