Some helpful information about Gold Filled jewelry: Although gold fill is a layer of actual 14k gold permanently bonded to brass using heat pressure, rather than solid gold throughout, it won’t tarnish or rub off, when cared for properly. From time to time, you may find it helpful to gently buff your pieces with a soft cloth to clean them, but not to worry, it isn’t gold plated, so won’t turn your skin green or discolor and is quite durable.
