Gold plated jewelry is very delicate and, like any plated jewelry, it can tarnish if not cared for properly. To make it last as long as possible, it's very important that you keep it dry. Chemicals from soap, chlorine, perfumes, makeup, and sweat react with the plating and cause it to tarnish. The pendants and minerals used are also delicate and are a product of nature. Take care not to drop your piece. To preserve your piece from the natural tarnishing property of humidity, do not wear it overnight and store in the velvet pouch provided.
