Ingen, it doesn’t mean that your jewellery is faulty, or that it is not real silver. If your jewellery has changed colour and has become black, it has oxidised.
Oxidisation, also known as tarnishing, is a natural process for your jewellery to go through and is a product of chemical reaction that is caused by the other metals that are mixed with the silver, reacting to natural and synthetic chemicals in the air and on your skin.
Your body chemistry can affect how quickly your jewellery tarnishes, which is why some people can wear earrings for years with no tarnishing, whereas other people can experience tarnishing of earrings after only a week of wear.
