Is 14K Gold-Fill the same as gold-plated?

Not only are their manufacturing processes different, but the amount of gold alloy used on Gold Fill pieces is different than gold-plated. Gold Fill metal is a layer of 14K Gold with a core of jeweler's Brass or Copper. Gold Fill jewelry has 100x more gold alloy than gold-plated and because that layer is so much thicker, it means Gold Fill jewelry lasts longer and stands up to wear and tear much better than gold-plated. The image below is a great example of the difference between metals. As long as the piece is well cared for, Gold Fill jewelry can last a lifetime.
