Why is my Tiffany necklace tarnishing?

Your Tiffany necklace is likely tarnishing due to the properties of its sterling silver material. Over time, sterling silver can react with particles in the air and substances that it comes into contact with, such as chlorine, salt and chemicals in skin care products and household cleaners. This reaction can lead to discoloration. Consult the care instructions that accompanied your necklace for advice on how to remove tarnish and reduce the risk of its return in the future.
