With the price of gold why would I not offer a more economical option for those that like to own lots of jewelry! Gold-filled metals are a great alternative that is shiny, durable and just as pretty as solid gold. A core of usually brass and sometimes sterling silver is used as the base for many, many (did I say many) layers of pure gold. This is a permanent bond and will not flake like a gold-plated item will. Much better quality.
