These pieces are made from copper, which is then plated with Fine Silver. This offers a more cost-effective way of getting that fine silver look. Copper is a metal which likes to migrate (which is why people believe it to be medically beneficial when worn). As such, the copper will show through the silver in time, going through a process of colour change; from silver to a reddish silver. These pieces will age and change with you. However, if you want to keep the silver look, you can coat it every few months with clear nail varnish.
