Wearing gold jewelry may change its color because of the alloy used. Pure gold remains bright and does not tarnish. However, other metals in the alloy can oxidize or tarnish with daily wear. Exposure to moisture and air can also lead to these metals showing visible color differences.
Another reason why gold jewelry turns black is due to sulfur exposure. Sulfur is present in pollution, certain foods, and even some types of rubber. When sulfur interacts with metal alloys in gold, it forms black tarnish. High humidity levels can also accelerate this process.
To prevent discoloration, take simple preventive measures. Remove jewelry before swimming or exercising. Store pieces in a dry place, ideally in anti-tarnish pouches. Regularly clean gold jewelry with a soft cloth to remove dirt and moisture. Using a mild soap solution can help, but ensure thorough drying afterward.
