1. Skin allergy: If the jewelry you wear contains electroplated black gallstones, and the electroplated layer falls off or wears off, it may cause skin allergy or itching and other discomfort.
2. Release of harmful substances: The electroplated layer of electroplated black gallstones may contain harmful substances such as chromium and nickel. If the electroplating layer falls off or wears away, these harmful substances may be released and enter the human body, causing harm to health.
3. Bacterial infection: There may be tiny cracks and pores on the surface of electroplated black gallstones, which are easy to breed bacteria and viruses. If it is not cleaned and disinfected in time, it may lead to bacterial infection.
